You need to find an 8x12x2 seal for the '90.

You need CR Seal #'s 3030 & 3930. Most jobber stores or bearing and seal places should be able to get them for you.

The wiring is the same.

You need to find an 8x12x2 seal for the '90.

He will have to wire in a TPS plug from the 91-94.

And depending if he keeps the IAC and junk, hell have to swap his 90 out onto it, or extend the harness off the firewall to plug into the 91-94 IAC.

The TPS and ISC connections are different between the 90 and 91+ both harnesses will need to be extended or adapters made. The 91+ TPS will hit the 90 fuel rail so you'll need to swap the fuel rail too.
