1990 4g63t motor to 1991 chassis

[AWD_Boosted4g63]

i just put my 1990 4g63 motor in a 1991 chassis, but the plugs on the wiring harness don't match up on my motor, i know that the 90 has a different throttle body, but what else is there on the 91 that i need to put on the 90 motor,
where can i get all of what i need????

This page should be helpful to you, although it is, 91 to 1990, You would still have to look at it the same way. Changing same parts as such.

Swap

This is what I know thats different off the top of my head..

-CAS
-Coil packs
-Ecu
-oil filter houseing in air/oil cooled

They would all have to be switched to 1991. unless you kept the 91 OFH that should just bolt up then.

You don't HAVE to switch ECU's IF you swap Pins 6 and 14. Easy either way...
