Before it happens, I know the LS Auto swap into an EG Auto is not a worth while swap, but it is done. Problem I am having is getting accurate information on wiring the TCM. I have an OBD1 P75 ECU with matching TCM. I ordered an adapter harness already, I am just trying to get it from the garage I used space in to do the swap back to the house while I wait for the harness to come in. Anybody? I have a 95 Civic EG sedan that had a D15 auto in it with the mini-me head swap.

 

Get it towed?

 

Trying to avoid that also

 

Well its best not to mess with the wiring since you have a custom harness on the way. I'm not sure why the diagram/layout is confusing unless you don't know what sensor is what.

 

The diagram is not difficult, the manual only shows 6 wires out of like 34 for the TCM

 

Dude........chill with the b.s.

 

What b.s.? It's all good, I can just wait until the harness comes.

 

There is no way the helms manual only gives you 6 wires out of both of those plugs, thats where I call b.s.

 

Oh, not Helms. Crappy Haynes. I don't have access to Helms

 

You haven't asked but I feel inclined to answer a different question.

If you swap a B series auto into an EG, you need to use an auto trans from a 92 or 93 Integra.

There is a how-to thread here on HT about a B series auto swap, in the outcome he has two engine mounts disconnected. That thread should be locked and deleted. He used the wrong trans and feels that missing two engine mounts is acceptable.

 

You can get the Helms at hondahookup.

 

Baller, the motor and trans are out of a 98 Integra and the ECU and TCM are from a 94-95 Integra

 

Baller, they don't have 94-95 Integra on HondaHookup

 

Got harness adapter and everything is hooked up right. Go to start and car will crank but no spark. It has power through the distributor but no spark. The adapter harness is top-notch, JKOBD custom adapter harness, so it shouldn't be any part of the problem. Double-checked all connections and they are as the instructions. Jason at JKOBD has been more than generous trying to help me figure the problem out. Any ideas?

 

Swap a known working ecu.

 

I have to get a hold of another P75. The only other ECU I have is a P28 and the car ran with that before that swap. Now the P28 doesn't even let the CEL go out. The P75 does though.

 

If the car started before the swap than you have an issue with the wiring, the engine already had issues cranking before, or you have the firing order wrong on the distributor, you're missing something.

 

You mean to tell me, you don't see a manual that has the yr 94 on there?

Total troll man.........total troll.

 

The engine and trans are out of a 98 Integra with the engine harness also.

 

And what obd version ecu are you running?

 

It's a major pain in the *** to wire that up correctly, it's a lot easier to just swap the car to a manual. If you must go ahead with it though here's the wiring diagram for the TCM:

 

Tony, I am running OBD1.

94EG8, thanks for the info. I will double-check them all. Thanks again

 

Thank everybody for all of the help. We finally got everything straight, except a CEL Code 4. We tried three different distributors and even hard-wired directly to the ECM. Any ideas?

 

Something iffy with the wiring, so you'll have to check that. If everything is wired properly than the distributor should be fine.
