Hey HT, I'm doing an LS swap into my 93 Vx HB. It already has the 4 wire 02 sensor rigged up, but the LS has a complete harness on it anyways. However, the engine harness only has 3 plugs going to the fuse box side connectors. Is this normal. The engine that was previously in the car, a b20b, had 4. It doesn't look like anything is cut. It is all OBDI. Im a bit of a rookie but I'm trying to soak it up. Thanks

 

ive got a b18b1 in my 93 civic EX coupe. When i did the swap i noticed the same thing about the LS harness, so I threw my origonal engine harness back on, and suprisingly everything pluged into the LS's plugs, the only thing I couldnt plug in was my VTEC plugs because obviously, the EX motor had VTEC, and the LS motor doesent. I dont know what the difference between the VX and EX harnesses is, but give it a shot. Ive had no problems, and have been driving it for two years now like this, with using the EX engine harness on the LS motor.

 

The engine harness that is on the b20 looks a bit rough, I kinda wanted to use the integra wire harness. Will that not work? Are one of the four plugs that are coming from that side for vtec perhaps? Thanks

 

can anyone confirm this?

 

sorry to bump up again but has anyone swapped a b18b into a 93 civic vx and used the integra engine harness?
