ls in 93 coupe

[werdupEGs]

Ok tracked down all the information we need to know.

I am currently using:

93 civic coupe
OBDII integra wiring harness
OBDI B18B

here is what I am trying to figure out. I have like 3 unused plugs. One I am sure it's just emissions stuff i don't have ,and the other probably secondary o2 sensor? But the wierd thing is that it has 2 plugs that can plug up to the TPS. What is this second plug?

The car seems to run fine how it is.

bled clutch and brakes, and took the car out.


It runs pretty well besides the fact that its open header.

I'm lettin it sit in my shop overnight and will check for any leaks tommorow. Then gonna do a full tuneup, timing belt, water pump, gaskets, etc.................... all fluids

checking the codes..

then putting the T25 on it.
