i did ls vtec on my 96 integra obd2,,, does someone no how do i run the cables to the ecu or harness... anyone have pic they can send me

 

What ecu you are you running? what engine harness? is the the integra a LS chassis

 

im running a p72 from a 98 gsr...ls harness but i pass all the vtec cables and everything i just dont know were they go in the harness... and i was wondering y the ecu is not letting me rev up higher then 5000RPM is it cuz the vtec is not connected?

 

Well with the sub harness all you will need to do is de pin at the ECU and re-pin using the sub harness. De-pinning is where you remove a wire at the ECU plug and re-pinning is where you put another wire back in that position. Since your car is an LS, I dont think you will need to de-pin anything at the plug, since you never had vtec, but you will need to add the wires from the sub harness into the plug, that way the ECU can tell your vtec when to engage. It's complicated, somewhat, but a very easy process. See what you have on the vtec is 1) ground, 2) Vtec Pressure switch, and 3) vtec solenoid,4)secondary butterfly IAB those are the four wires you need to wire up unless your running a gutted intake mani dont worry about the secondary butterfly. The ground, just needs to be connected to a good ground. The pressure switch needs be pinned into the plug that goes into your ECU, and the same goes for the solenoid wire. Your solenoid is that cylindrical thingy right in front of the distributor if you're looking at the motor. The pressure switch is just under it with two wires (ground, and signal). Now you may be asking where to pin these, well you need to look up the pins on your ECU. Just do a google search, and search by your ECU whether it be a p30, p28, p72, etc...these will tell you which are which. To search the ECU pins, just search up the ecu + pinout (ex P28 pinout).

 

Or if you want just an idea for you... You can by a vtec subharness from Ryan at Rywire... good guy an does great work... Ryan@rywire.com

 

how much they run for

 

i think i pick one up for 75 some months ago.. they make it look oem so no messy wires hanging around in you engine bay.... an they will also include a diagram with it on how to do it if your still having problems wiring it up...

 

Check my signature I have them for $30 shipped

 

im having hard time i have everything ready but everytime i connect the 98 gsr ecu it only raves up to 5000RPM ... can it be that i have the ls troudel body??? or wat can it be
