Ok kinda Confused on the the Wiring for the LS Vtec. I have a LS Bottom Block with a p72-1 Gsr head. Now for the Main wiring Harness what should i use. I was just going to use the Stock wiring harness for a 92-95 Civic because that could have worked for just a LS swap in a EG but since im using a Vtec head what kinda of wiring could i use. I think the Head is OBD-1. I dont think it would work but i do have the main wiring harness for a 97 LS motor which i think is OBD-2. Also can i use the LS ECU in the Car or what kind of ECU could work with this setup. Sorry for the Confused Questions. But could i get some links on this also i need a link for a Distributor and where i can buy them i need the distributor for the GSR head. thanks

 

I have the same setup. I have a Ls bottom end with a B18C Vtec head. im running a 1997 Integra P72 OBDI ecu with a OBDII to OBD1 conversion harness. I am using my stock 1996 civic wiring harness. The proper ECU is the Vtec model for you car. 1992 - 1995 A-4 Vtec Soleniod, D3 Knock sensor,d-6 Vtec Pressure. All you have to do on the wiring is as follows:

1. A jumper wire running from the appropraite pin in the ecu to the vtec control solenoid which completes the Vtec activation.
2.Hook up a ground for your knock sensor or install a knock sensor.

And thats about it.

 

Run a P72 with Vtec
Your harness should be OBD1 so your standard harness will be fine.
What car is it give me the model and I will let you know exactly what you will need

 

Well i dont have the main Wiring harness at all.But the ls/vtec build up will be in a 92-95 eg hatch. i dont have the car yet but soon. And i want it to be a DX or VX. But are those models OBD1. Can i get some help on this cause i want to do it. But the running wires from the ECU seems kinda hard can you show me some pictures and information thanks.

 

Any honda made before 95 is a OBD1 car. 96 and on is OBDII. Its much easier to just run the jumper cables from the ECU cause the only other way would be to change out the entire harness to the Vtec harness for your model which is way more of a mission.

CIVIC-EG6,EG9
92 - 95
B16A2
B18C1
LS/VTEC

(OBD-1) P08,P28,
P30,P61,P91

Those are the ecu's you can run for that swap. They will hook up straight the the wiring harness in that civic. Then all you will have to do is run the two jumper wires. Hey who ever said anything was easy. Thats the easiest way to do it.

1992 - 1995 A-4 Vtec Soleniod, D3 Knock sensor,d-6 Vtec Pressure. Those are the pin locations on the ECU for each wire you will have to run. You can have the ECU chipped which will take away having to do the Knock sensor. Hope this helps

 

Where can i get a Chip to do this. And it does help out alot man thanks

 

use the search button, go to honda-tech.com and use the search button.

 

Ebay sell tons of diffrent makes and models you just need to find the right one.

 

I have a 94 integra with a b18b1 and i am about to purchase a b16a head to do a lsvtec swap and i know i need to run a line from the block to the head for oil pressure and will need to get a new ecu and jumper harnest but im not sure if thats all i need to do. is there anything else that i will need to get and how do i wire the vtec solenoid to my ecu. Sorry about all the questions just new to the honda world and im extremely interested in learning more and even goin to school but just wanted to be able to keep up with a couple of my buddys.
