On my 88 crx i just bought the guy that had it has done some interesteing wiring. IVe figured most of it out but im down to two very puzzling wires. FIrst i will explain the location of these two wires. ALright we are talking about an SI first as well, now if you follow the injector wires towards the resistor you come to an 8 wire round plug. 6 of the wires go to a square plug. THe other two are the mysterious wires. One is black with a yellow stripe, and one is blue , with no stripe. They are cut about 4 inches away from the round plug so i have no idea what they are for or where they go......


PLEase help me as i knwo they obviosly go somewhere....

PLEASE!!!!!!

 

They might be the wires for the Thermosensor on the back of the block. I remember one wire being yellow/black and maybe the other black but maybe the one I thought was black was really blue.

I looked at the EACV also, it has a black/yellow and a blue but the blue has a yellow stripe on it.

 

well i know that on my friends CRX they go into the harness that goes through the firewall......

THis is so frustrating......

 

probably for a/c

 

Car doesnt have A/C and neither does my friends, and like i said his same two wires go into the firewall.

Heres a uestion does anyone have a wiring diagram for this???

 

if they go to the ECU, the only all blue wires are the alternator output signal and the fast idle control solenoid valve which is only on the 89-91 Si - 88 does not have this valve - could be someone switched to 89-91 harness? any black or black with stripe is usually ground
just checked the wiring diagram and the blue and the black/yellow at the plug you are talking about are for the fast idle control solenoid

SO in my 88 if its the fast idel thing i dont have to worry about it?? And what about when i do my Z6 mini me, can i still leave it alone??

Thanks so much jlicrx

 

check the helms it might help you.

 

These are distributer wires. The black/yellow is fat right? This is your coil power. The blue wire is your tach signal.
