Wiring up power windows and door locks

[nlauffer]

I went across the street to Napa to look up some relays and sockets and these are what I found.

Echlin Brand
Relay - AR143  $13 each
Socket - EC23  $13 each

This puts you just over $100 plus some wire and a fuse to accomplish this.  I think while I have my truck disassembled I'm gonna wire this up.

This is why I posted my find. I was hoping someone else would post other options. Does anyone know the quality of the above relays?

Thanks for all the help I appreciate it. As I read on I'm starting to get a bit confused, but this weekend I think I'll just dive into it and see what I can figure out with those diagrams. It's a little embarrassing I am starting to get lost with what you guys are talking about because I am a mechanic but electrical has never been my strong suite.  Do you think those relays on eBay are decent ones? I think for that price I will order them and if you guys think the relays are junk I will just use the sockets and buy good relays.

Just finished wiring up the relays for my windows. It is amazing how much better they work. Truly unbelievable.

Would you post some pics. I am curious to see how you mounted the relays and where you spliced in the wires

[frotosride]

I wanted to keep the factory style connectors inside the switch connector so I just used butt connectors and solder. Once re wrapped it looks factory

Wires rerouted...

Bosch is likely the best ones to get and make sure that are 5-pin.

Just so you know Bosch relays got bought out by Tyco if I am not mistaken. So I found these which are Tyco/Bosch and are a good price for 5 relays and harnesses.

here's how I mounted the relays. I cut out an aluminum plate and drilled holes to mount them. from there I just used Velcro to mount them to the air handler.

mounted on right side of air handler. A little warpping and loom and it will look good.

I am in the middle of implementing this wiring configuration.  I have only one question. Am I reading the diagram correct that terminals 87A and 85 on all four relays are grounded?

     Post a link to what diagram you are referring to please.

Correct.  But, there is a caveat:  Are the relays you're using surge clamped with a diode internally connected between terminals 85 and 86?
