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.
