Ok so i have a 1990 ef hatch.. its a dx ..shitty d15b2 ... i have a 1995 b18b with a cable trans and i have the mounts and the shift linkage to make the swap possible.. i want to kno how do i go about the engine harness part.. the plugs are different from the ones that are on the engine... and the ones that are in the engine bay.. i kno i need a jumper harness obd0 to obd1.. but thazz for the ecu right? ... but wat can i do about the harnees that comes from the engine to get plugged in to the connectors in the engine bay??

 

was the d15b2 dpfi? i cant remember, if not you need to add those injectors in. Check out rywires kits he makes it easy. Rywire.com i think

you'll need a distributor adapter, or new plugs. O2 sensor wiring (from 1 to four i think) and of coarse the jumper harness for obd0 -1

 

so i dont gotta change the harness on the engine?

 

you shouldnt need to swap your entire harness out. just add injector plugs if you need them, o2 sensor, and a distributor adaptor, along with the ecu jumper.


check out this tech article, its for a b16 so yours will be simpler without vtec and knock sensor. good reference though.

no you don't. but you will have to modify it. right now its setup for dpfi (2 injectors) and you need to alter it to support mpfi (4 injectors).

after that you will then need an obd0-1 ecu jumper w/ subharness for 4 wire o2, etc. as well as a 0-1 ecu adapter. you can pick that up here..
