Here's where I'm at. I have a 1990 Integra that I'm going to use to rebuild my 1991 Civic that used to have a b16a swap previously installed. Actually it still have most of the old B16a installed. The head is gone but the block is there.. the wiring harness is the only thing that I am honestly worried about when it comes to doing this swap. Hell my civic is more prepared for this whole thing than my integra ever was..

Please respond if you have any knowledge of b16a wiring harnesses involved with a 1991 Civic. I might call on you online if I have any trouble getting the bad boy started after doing the complete swap.

Secondly.. anyone know .. that relatively local where I can get a good condition b18a or b longblock?

 

Install ls motor, plug in your wireharness, leave yor vtec specific plugs unhooked, wire o2 sensor to correct pin on ecu, plug in ls computer, drive you car. Its a simple swap

 

The Civic already has a damaged b16a inside.. can i just pull the harness off it and reuse or is it easier to just pull the Tegs b16a harness and run through the civic? I've seen this swap done quite a few times but I've never done all the work.. the electrical is the only part I worry about. I've spliced in my own VAFC's before so I'm familiar with the wire coding and such..

I'll check back if I seem to have any problems.. I'm just getting both cars in the air right now.. (no lift... and no cherry pickers... doing this an... interesting way)

 

Ok.. here is the situation right now...

Swapped the b16a out of a 1990 Acura Integra.. took the harness that was on the motor in the teg and took it over to the civic. The civic's harness was spliced into so I wired up the Knock sensor, O2 Sensor, and hooked up the v-tec silinoid (sp).. everything there is good.. now if you are familir with 1990 acura integra's and 1991 civics.. here is the problem I think...

The left side of the motor standing in front of the car.. near the fuse box under the hood, there are 2 connections .. one is a 10 pin (5 stacked on top of 5) connector and a roundish connector. This is the civics... the integra had the roundish connector.. it had like 10 pins in it (civic is the same) but the other connector on the Teg is just a round 2 pin connection with a black/red and a black/white wire. I do not have the Teg manual and my civic manual doesn't have my year exactly wiring listed.

I took the round connection off the Integra's harness and spliced it into the civics.. but since the civic had 10 wires on that stacked connector.. I had to use the two wires that resembled... the black/white wire was there.. but it had a black/red on the integra.. if you know anything about this.. let me know..

Current issues I have on it.
1. When you turn the key to ignition II it turns the car over instead of just having the car in the "on" position.
2. It still doesn't start... seems to be trying real hard too... as if perhaps the ignition isn't actually firing. I am going to trouble shoot that when the sun comes back up.. and the mosquito's stop attacking.. (Damn texas bugs get on my nerves)

Anyways... any help you can give guys I will appreciate!

 

Looks as though I am gonna have to just redo this harness because the harnesses are completely different in location of wiring. Colors are the same hooked up to the same parts of the motor.. but the wiring out to the car at parts goes to opposite sides of the engine bay.. I figured since the civic had a b16a in it already it would be an easy swap but the integra setup b16a wasn't anything like the wiring for the civic's b16a...
