Vtec wire on b18 swap.
Hey guys, i need help. I am a dumbass and after searching on here i found alot of help on why i'm getting a cel 21 after my gsr into ls obd1 swap. I need a vtec wire or wires. What i couldnt find was specific instructions on how to do so. I put a jdm b18c1 in my 94 ls that had no motor to begin with and i used a usdm gsr harness. Would i need to add wires from the end of the gsr harness through the firewall to the ecu? or would i need to add them altogether ??
Please help, i want my vtec!!

Nah, its not for the map sensor.. that is already plugged in... i looked today and its not my evap thing either. There is no plug on that. Im wondering if it;s the wrong evap thing bc i pulled that out of a gen5 civic ex. I really dont know.. anyone with a gsr have a pic of theirs?

Since you are using the GSR harness and I assume a P72 ECU, you only need to complete the wiring from the shock towers to the ECU. You will need to trace the sensor wiring from the sensor plug to the end at the shock tower plug to follow this wiring:
VTEC Solenoid: GRN/YEL - A4
VTEC Pressure: BLU/BLK - D6
Knock Sensor: RED/BLU - D3
Intake Air Bypass (IAB): PNK/BLU - A17
The ground for the 2nd VTEC pressure switch wire and the 12V+ for the 2nd IAB wire will be taken care of since they both junction to existing wires in the engine harness that provide the proper signal.

Re: Vtec wire on b18 swap. (VTECVillain)
Thanks alot guys, i think i have it wired in the way it should be. It was throwing cel 21 and 22 when it wasnt wired up, but since i added the vtec sol. and vtec oil press. wires, the cel's went away. I dont have a half shaft that works right now, so i cant drive it to test it out, but i should have it on the road by sat. depending on when i get the axle.
And i guess those plugs do go to the abs because i took it out completely. I jsut dont like abs.
