I have a bridge pickup from Peavy tele copy that I'd like to wire into my old squire stratocaster. The bridge pickup that was in it only had two wires and the peavy pickup has red, white, black, green, and bare. I have no idea how to go about wiring it to the strat. Can anyone help?

Yes.
I'll help you help yourself (then you'll know "how to fish").
It sounds like the Peavey pickup is a dual-coil stacked humbucker.
The first thing that you should do is to use a multi-meter to measure the wires in pairs (including the bare one) to determine which wires are connected to each coil. Wiring a guitar without a multi-meter is like driving with your eyes closed......(while it may be "thrilling" to some, it's not highly recommended).
There will be two wires per coil, and the bare one probably won't be connected to any of the others. While you're at it, also record the resistance of each coil.
With two coils, there are four possible wiring combos for this pickup; 1. Both coils in series (stronger/darker sound, humbucking) 2. Both coils in parallel (weaker/brighter sound, humbucking) 3. One coil, (weaker/brighter sound, not humbucking) 4. The other coil, (weaker/brighter sound, not humbucking)
There are also phasing issues (an AC equivalent of DC polarity) that must be resolved within the pickup (if both coils are used and they are out of phase with each other, the sound will be extremely weak and tinny), and with the other pickup(s) as well. These are easy to fix.
First things first. Let's measure the pickup and if possible, post some digital pics of it (it may well be a standard aftermarket pickup where the wiring can be easily discerned).
Are there any names on the pickup?
What model and vintage is the Peavey guitar? There may well be wiring diagrams on the Peavey site.
OH, and will the Peavey pickup actually FIT into the Squier (a minor point, eh)?

I'm very sorry, I didn't make this clear earlier, but it's a single coil pickup with four wires plus the bare ground. I have never encountered any other single coil pickups with more than two wires. The pickup itself doesn't have any kind of name or number on it. The guitar was a tele copy and this pickup will fit the bridge position of a telecaster. It also does fit into the pickguard for the Squire. I had to drill the holes for the screws since they are arranged differently on the tele. I do appriciate any help you are able to give me. Even if it's just findind a diagram of how to wire a four wire pickup into a strat. I didn't have any luck at the peavy site but I probably just missed it.

beltzer, Trust me, it feels bad to a newcomer here, then have to set him straight. Trying to keep this as gentle as I can, I'd like for you to do one of two things: either do as ChrisK suggests above (get a meter and test the leads), or simply accept it as an article of faith that a coil that has only two points of connection (the two leads). It doesn't need, nor indeed, can it have, four leads plus a shield (the bare wire). There's no place to mount the extra leads, because by definition, that would make the coil into at least a pair of coils (and it could get worse, but we won't go there ). I think you'll find that you have an after-market pickup that is a stacked humbucker, made to look like a normal single-coil pup. Chris and I know these things real well, he and I each have a trio of them ourselves, they came stock on our gen-you-wine Fender Stratocasters. I know for a fact that several other members here have the same thing, although they may not all be Fenders. Lacking a meter in your hands, try this: just lay any pair of leads across the two contacts of a guitar cable, the other end being plugged into an amp that's on. Be sure that your hands/fingers are not touching either lead being tested. Now, tap any of the polepieces with a small screwdriver (or a key, or a......). What'd ya get? Do it again, with another pair. And while yer at it, write down the results - colors of each pair, and the results. When you're all done, you should have 6 readings (3 combos for the first wire, 2 combos for the second wire (no duplication necessary), and the final pair, all that makes 6 readings, right? In the end, I'll be an extremely surprised little boy(!) if you don't get two pairs of wires giving you some kind of clicking sound when you tap the polepieces. If only one pair produces this sound, then the remaining pair belongs to a coil that has a broken wire somewhere inside. Time to put the pickup to the test! ;D HTH sumgai

I see, I do have a meter and I will do that. I'm sorry about not understanding at first. I'm ignorant and I know I am, it happens. Being ignorant is exactly the reason I came here. Thank you very much for taking the time to help me.

In no way was I trying to rebuff you. I was just starting down the linear path to knowledge about your 4-wire plus ground Telecopy pickup.
This less-than-onerous journey is necessary since we don't know much (yet) about that there pickup, and any published wiring diagram is moot until we know just exactly what the wires go to. Different pickup makers often use the same wire colors for different coil connections. We still don't know what we don't know.
And, the next time that you encounter a similar issue (or encounter one that is following this path for the first time), you'll know what to do (or how to help).
In time, you'll reach the point where you rarely search for, or download a wiring diagram since most of it becomes patently obvious.
We all stand on the shoulders of those that have come before us.

I really appriciate your help and patience with me. The black and green wires were tied together while in the Peavey...so before I go to testing, should I seperate them? And what readings will I want to see from the multi-meter?

Hmmm...sounds like the coils were wired in series. Leave them together and measure from the black and green to the red, and then to the white. You should measure about 5K Ohms to perhaps 10K Ohms or so (use the 20K Ohms scale). Then separate them and determine the wire pair for each coil. It may be green/red and black/white. See if the bare wire is connected to any of the four.
I had originally begun to think that you have a Seymour Duncan or perhaps a DiMarzio pickup. But, the journey is also a destination.
With the black and green tied together and the coils in series, the red (or white) will be the output and the white (or red) will be the common (ground) connection. You may have to reverse these if both pickups sound thin and tinny when both are selected. Since the green and black were tied together, we also now know the relative phasing between the coils.
Finishing the measurement exercise will definitely identify the exact wires for each coil and enable parallel wiring if so desired (it should be tried anyway).
Are there any markings or numbers on the bottom of the pickup?

Ok, I have figured out the wire pairs. Your guess was correct, the pairs were red/green and black/white. They each measure around 9.2 on the 20k scale. The bare is not connected to anything. There are no identifying marks whatsoever on the pickup.

Golly gee...I found a diagram I had made of the peavey's wiring before I removed a bad pot. It shows the black and green being connected with a wire from the old neck pickup to one position of the switch while the red wire is connected to a different position on the switch. The white wire was used as a common ground wire.

Post the diagram or at least the link thereto. Great, thanks. Therefore, the following is deductible (deduce-able?): RED Top coil output GREEN Top coil return BLACK Bottom coil output WHITE Bottom coil return The switching in the Peavey is using the series coil wiring (RED, both coils) for some pickup combinations and the tapped (GREEN/BLACK, the bottom coil) for others. For SERIES coils; RED Output GREEN Wired to BLACK BLACK Wired to GREEN WHITE Common For PARALLEL coils; RED Output GREEN Common BLACK Output WHITE Common Now, to ensure the correct phasing with the other pickups on the recipient guitar, the Output and Common connections may have to be switched. You can do this on the transplanted pickup or on the other two. Since the transplant has more wiring complexity, you probably should switch the two wires coming from the other two pickups IF NEEDED (easier is). You'll know if it's needed if the combinations of the transplant and the other pickups sound weak, hollow, and tinny. Now off with you, go get to work a' wiring! (Unless you would like to discuss what wiring combinations that you would like.)

Chris, Deduced. "Therefore, the following is deduced:" would be proper English. If instead you are going to predict a future result, instead of reporting the present results, then you can say "Therefore, the following might be deduced:", that's also proper English. You're welcome. Professor sumgai ;D

By george I think I've got it. I wired the pickup in with the two coils in series. I havn't put strings on the guitar yet, but the pickup seems to be working fine. There is an incredibly annoying buzz which I assume is grounding problem or just bad connections, as I am bad at sodoring. But I can take care of those. Thank you for all your help. You have no idea how appriciative I am of you taking your time to (frustrating I'm sure) explain to me what I needed to do. Thanks a lot.

Having put strings on the guitar, it does sound alright. The middle pickup is louder than the bridge...by a lot. But I think it has a lot to do with the fact that the middle pickup is a lot closer to the strings right now. Other than that, things are great. Thanks!

Yeah, but if'n I place a varying magnetic field onto a pickup I can induce a current into an inductor, so why can't I deduce something from a deductor?

Think of it as reductive seasoning.
Have a good even'ing.

Chris, Because in order to do that, you have to be a licensed deductive. Which of course is not to be confused with an unlicensed seductive. Neither of which are deductible. ;D
