on the connector that is on the driver side by the resistor box the c313 connector ????

theres a pic i have two wires hanging from the previous owner hacking into it im throwing codes 10,6 , and nine 9 anyone have any diagrams or have any idea where the wires run

 

Wow that $hit is all hacked up. That is part of the engine harness some of those wires got to the fuse box and some to the ecu.

 

any clue where to? the fuse box in the engine compartment??? or under the steering wheel?

 

oh yeah by the way this is a 88 crx si

 

AnyonE??

 

your car may be an 88 Si, but that engine harness is not from an 88 Si - round 8-wire connectors were on 89-91 - the 88 connector is a square 6-wire and looks like this:



the reason the 89-91 had 2 extra wires was for the Fast Idle Control Valve which the 88 doesn't have - the black/yellow and blue wires are for the FICV - there are no wires in the 88 chassis harness to connect these wires to - for the car to run, you don't need the FICV - the codes you have aren't related to that connector - the wires for the sensors that are throwing codes are in the connectors on the passenger side - make sure all of the wire colors match on both sides of those connectors

 

i was reading in the manual that 88s and later have a eacv, on the back of the intake with the same color wires.black and yellow and the blue/yellow one said that the black and yellow went to fuse #14 and the other one went to the ecu to a11, maybe this?

 

also was looking at the ecu in my car and it says its a pm6 and it has 89 in a black ink stamped on it

 

if it helps i believe there was a ZC engine in it before have anything to do with it?

u need to get the electrical service manual for the car and sort through your harness tracing all the wires and everything. Time to get real familiar with your car.

any idea where i can get a book just on electrical?

 

Yep go to this link,

If that doesn't work, just go to this and fill in the info, http://www.helminc.com

U want the electrical troubleshooting manual.
