i own a custom car shop but this is my first major job on an import do i need the 93 integra engine harness and ecm and will it plug into the exsisting 88 crx harness

 

search on this forum for "mpfi swap" & "obd1 conversion"

you must use the crx harness and modify it for the 93 teg electronics. swap the teg's distributor & injector plugs over to it.

then the ecm and everything will plug right in and work

 

i dont have the original engine harness but if i had one all the b18 sensors would plug in? do i keep the crx ecm or use the teg

 

most of the sensors would plug in, yes. the fan switch moves from the back of the block on the crx to the thermostat housing on the teg. you need to swap that plug as well.

use the teg ecm (ecu in honda world)

it's a REALLY good idea to start with a harness from the same year / trim / model vehicle and go from there

 

what year is the engine?a 1990 or 1991 Integra changeover would be the easiest for you guys. otherwise, go here:

They sell an OBD-0 to OBD-1 conversion harness, along with everything else to make the swap real easy for you.
