Hey guys, need some help...Tried searching the sticky's but couldn't find what I was looking for. 'ecuman' has helped me out a lot so far regarding the immobiliser bypass, but I'm now stuck...details below:

Car is a 99 civic coupe ls, originally running a Y7, with OBD2B ecu & loom.

Donor Y8 engine, loom & ecu came from a 97/98 sri (I believe). Loom & ecu are OBD2A.

The Y8 engine & 2A loom are both fitted, however...Part of the 2B loom seems to be incorporated with the interior loom, it also seems to control the fuel pump relay, so I'm left with this:



...an extra ecu plug and a car that wont start. Thought originally it was the immobiliser in the 2A ecu, which has since been bypassed, but still no sign of life from the fuel pump (which I now know is down to the loom).

What are my options?

-Take it all out and just do a mini-me swap?
-Convert it all to obd1?
-Is it possible to convert 2B to 2A?
-How do I incorporate the extra ecu plug?
-What loom/ecu combo do I need to run to keep the Y8 and run vtec?
-Other...lol

Obviously I'm looking for the least time/money consuming option but either way I need to get back on the road, just don't know what to do next...

Any help or input would e greatly appreciated guys!
Thanks,
Nick
