I have a ls vtec with a gsr head, and im using a ls harness. Now i know i need to pin the secondary iab to pin a17 however im not sure which clip to use on my harness? There is 2 circular clips that are close to eachother in the general area. I really need some advice or a diagram for the ls engine harness. Any help is appreciated!

 

a LS harness will not have a plug for the IAB you will have to add that yourself..find a round 2pin connector and run 1 wire to A17 and the other to ground

 

If you don't have to pass emissions you can do it the easy way and move pin A20 to A17 and plug the purge solenoid connector into the IAB solenoid (wire colors are yellow/black and red) if you need to pass emissions than get a 2 wire round connector and run one wire to pin A17 and tap the other one into any of the yellow black wires that terminate at the driver's side rear of the engine compartment.

 

ok thanks man, and emissions is not a problem so i will do that. And also i have a jdm vtec selinoid that doesnt have a pressure switch so i found one of the 3 pass side harness clips that has an open pin on both sides so i was thinkin about just pinning it through the harness, but my car is a 92 ex so its already wired i just cant seem to find the green/black wire where the engine harness and car harness meet. thanks alot guys..

 

green/black? In regards to vtec? The vtec solenoid wire starts out at pin A4 at the ECU, orange/white wire to the chassis harness side of the shock tower plug, on the engine harness side to the vtec solenoid its green/yellow. Its the top plug of the 3 shock tower plugs btw.

 

ok. I am using a ls harness so then i can just re pin the 3rd clip and run my selinoid wire into the pin that meets the orange/white chassis side. And i meant to write green/yellow sorry. Thanks for the help man i have been trying figure this out for a couple days now. Thumbs up!
