Icon7 B16 swap Loom and Ecu setup

Hello, Im just after swaping a b16a2 engine from a 2000 Em1 civic into an 1998 ej6 shell, I cant seem to figure out the correct loom and ecu set up, I know the ej6 chasis is obd2a and the loom from the Em1 is obd2b, so do I need to get an obd2a engine loom? What ecu do I use then without effecting the immobiliser, Im very lost any help greatly appreciated.

you need to find schematics and ecu pinouts for both cars and figure it out. Not hard just takes alot of time=]

I have a b16a2 swap with a d16 harness a an obd2 ecu can i just use a conversion from obd1 to 2 onto the ecu or do i have to replace the whole harness.it bogs out some times so i think its cause the harness. Besides that it runs fine.

Use the engine harness that came with your 1998 Civic... and move/modify/lengthen/shorten/add the necessary plugs and wiring to make it all connect to the EM1 B16A2 engine and drop it in. Get the needed plugs from the EM1 engine harness. Trying to make the EM1 engine harness work in the '98 Civic is a giant mess, so unless you are really good with wiring, I advise against this.

That's good to know. I was going to take the entire engine harness and hondata from my em1 and engine and drop it into my 98. I guess I'll get both engines side by side and modify the d series harness.

Thanks for the reply, what ECU must I use then? Would I have to get an Obd2a ecu from a b16 and would this plug into the ej6 harness?

I'm guessing by the terminology that you're somewhere in western Europe. If you had an MPFI D-series you can modify the original engine harness and use that. If it was an SFI D-series you wont be able to. If you have the complete EM1 donor car you can swap the engine harness, cabin harness and door harnesses into the EJ6, you just can't use the engine harness by itself with the EJ6 cabin harness. Some of the immobilizers are easily bypassed, some aren't. The European stuff is often different than North American. If yours uses the red learning key I don't believe they are easily bypassed.

Thank you, yes my engine is mpfi d series, I'm not too sure what I need to modify on the d16 harness?, and would I also need an ecu from a OBDA b16 instead of the one from my Em1?
