i just got done putting a gsr in my ls. i been lookin for a while now but i still can find what i need to know. i been work on hondas for a while now but i never done this before.. ((hard wiring)) what im trying to find out is. does it matter what side of the pigtail i hook up the power. and how about the ground for it. does it have to go back to the ecu or can i just ground it on the block. gonna be hookin up the iab, vtec silynoid , pressure switch and knock sensor. i got the pin out of the ecu already. just trying to find out if its safe to just ground it to the block. does the power have to be on one side or another on the pigtail. thankz.. really need to know. almost done. just this and finding a p/s.. bracket. then done.. haha.

 

dam all this honda head and no one knows. ****. well i hooked it up and it works great. no check engine light on.

hes not look for wiring diagrams as you can read he already know where it goes.. his question is can he ground the wires straight to the engine instead of splicing it with another ground wire.. and the answer is that you should ground it with another ground wire.. I did all the wiring already cept that I cant find the IAB solenoid. I dont know where its located on the manifold.. does anyone know where its located at?? so I can pin it to a26

 

follow vacuum line from vacuum pot connected to IAB valves... it will lead you to solenoid underneath intake manifold.

ground is common and you can ground IAB solenoid anywhere so long as it will ground 12v. Read: Ground on thermostat housing.

 

as for the ground on the block is perfect!!!!
