I got power doors off of a 97 blazer from the junk yard i hooked the locks up using 2 relays. I attached a picture of how i did it. I was wondering what i would need to do and what wires i would have to hook up to in order to install a key less entry. Thank You. 2000 s10 power alarm -- posted image.

did you wire the switches to have a positive pulse output?

Judging by your diagram you connected 85 from each relay to one switch and 86 to the other? This shouldn't work in theory to actuate the locks. Am I just misreading what you've illustrated?

I would suggest that you wire the door switched wires to terminals 85 on their respective relays - also you can connect the (-) lock/unlock outputs from a keyless entry unit to those same terminals. Terminals 86 would go to 12V constant. The switches would also get a ground input if you haven't done that already.

thats kinda how i thought you had it, but i wanted to make sure. all you need to do is go to the relay section on this site and look at the setup for doing door locks for a 5 wire reverse polarity system. you will need 2 more relays to do it. wire like it shows and use the wires coming from the driver side door switch that go to the 85 terminals on your relays.

If you don't care about doing driver's priority unlock, you should be able to get by without adding any more relays.

If you get a keyless entry unit with (+) outputs, you can connect both 85s on your current relay to ground, and wire both unlock/lock outputs from the switches as well as from the keyless entry unit to their respective terminal 86.

actually, Chris, im not sure he can do it that way. i was looking at his setup again and its a 5 wire reverse polarity. so his switches rest a ground until he presses them. im not sure, see what you think and if im wrong, but......if he were to connect the switch outputs from both switches to 86 on his relays if he were to press lock on the driver side switch, the wire connected to 86 from the passenger side switch is resting at ground......which means........ZAP, instant short. if he connects his positive outputs to terminals 86 and the unit puts out its prospective pulses for lock/unlock to terminals 86, well......those terminal are a ground. again a short or maybe even destroy the brain. the only way i can see to do it is with 2 more relays. i could be wrong though.

dont wire the second set of relays like that. do them like this. cut the wires from the driver side switch that go to terminals 85 on your first set of relays and wire the cut ends to the second set of relays like shown below.
