89 computer is a SBEC so it won't just plug into the GLH if it has 85 wiring harness becuase it uses a logic module. You'll need a logic module from like a TII GLHS I think.

 

might as well keep the 85 in. Both are 2.2s. The 89 T2 has the charge temp sensor, but its not impt. And unless you manually run a wire from the sensor to the ECU (since the 85 harness wont have that plug), you'll have a check engine light to stare at.

And yes, you'd need an 89 Omni harness b/c it's SMEC like moreRICE said. I just woke up so im not thinking. But if you get an 89 omni harness, it wont be turbo so some things might be off there. I'd just use the old one since you'll be doing fuel and boost manually anyway probably

 

Id try to find a GLHS Stage 2 logic module. (4SFED has this in him!)

That way, you wont have to change any wiring and can use the same power module. The 89 will require wiring changes and a switch to the SMEC setup.

 

did somebody say neon??

 

anybody??

 

no

 

well fine then...

 

i'll just sit in the corner and talk to myself....

 

or play with myself.....either way....
