now this is the plug on the right im talking about the one with yellow green please read below , also anyone know what that other one is for i had unpluggen on my other swaps and never ran any codes or ran funny at all.







Ok im going to put my b16 in either tonight or tomorrrow but i have one last thing to wire up. now i have a question about around where the thermostat is, there is a plug but on my obd0 harness i dont have that plug. Now this block is a a2 block so a little newer, now on the a1 block there was this plug that i have pictured now does that just get wired into by the thermostat? cause i dont have a spot to plug it into the back of the block on this new block



this is where i think it should go by the thermostat. its that common brown clip. What color on top what color on bottom?..




hopefully i get this solved and i can finish this off.

 

thats the switch for your engine cooling fan. d series is on the back of the block next to the oil press sensor. b series and obd 1 d's (like my d15b) the fan switch is on the thermostat housing.

 

plug on the left goes to a purge solenoid that the b series doesnt use. its on the d

 

do you know on the switch which wire goes where or does it really matter? like yellow/green top and black bottom or what?

 

do you have a plug to go on the fan switch? im not sure how else your trying to attatch the wiring. you need the plug with some wire still attached and you extend the factory wiring to reach

 

Oh ya no worries on that I many harness that have that common plug, I'm using a a gsr one atm repinning it all it obd1 . I just don't know what color wire goes where on that thermostat housing?

 

doesn't matter where the wires go on the fan switch. all it's doing is completing a circuit.

the connector on the left in your first pic is for the fast idle control solenoid valve (ficsv) and won't be used. and you won't get a code from it being unplugged as you've already determined.

 

I'm a little confused, got any more pics of the harness in the engine bay?

 

uhhh doesnt that plug already have wires on it? just attatch the harness wires. and what do you mean repinning all obd1?
