I ran into a problem hooking my door locks up to my remote start unit. I got the wire diagram off here. I found the wires that control the door locks. I am using relays for the polarity. I am able to unlock both doors with the remote start unit, but my main problem is locking the doors. there is a current going through, but it is only around 7.5 volts, and thats tested right off the relay post. I have no idea how come the current is so weak. The constants into the relay read 12.2. anybody know whats up with this??

Not sure YEAR of P.U.
If you have 12 volts to PIN 87 where did you check from there (PIN#?)?
If it is 5 wire Reversal, check PIN 87a and 30, U may have them reversed

its a 97. at the output on the relay i am getting 12, but at the hookup i am getting the lower voltage. i have it setup just like the unlock, but the unlock works just fine.

I'm taking it U are using 5 wire Reversal. If so:
U either are on the wrong wire or PINs R reversed.

sounds like a connection problem......make sure you have the wires wired up the right way for the lock wire
