Best way to do it is prob an 1989 engine harness, but you'll need the whole thing from the EEV out into the engine bay, alone with a MAF, inlet tubing and computer.

Cheapest way, is the IST mass air harness

IST Products


Pick up a 1994-1995 70mm MAF, a 70mm MAF adapter, the air inlet tubes and a used A9L or A9P depending on your trans and you are good to go. You will have to run a few additional wires to the VSS and fuel pump relay though..with any conversion

So get one out of a 89

or get this kit below?

or do i need both to get it to work


which one?

Part Number CH-8611-F, for OBD-I EEC-IV connectors (4 terminal oval)……....................................$39.95 Part Number CH-8612-F, for OBD-II EEC-V connectors (4 or 6 terminal rectangular)…....…..........$49.95 Part Number OA-9666-F, (6-wire add-on kit if you are using the internal ACT sensor )....................$4.95

Either one. You can either go with the OEM 1989 engine harness, or use the IST harness.

I've installed the IST harness'es before. They work fine and have good instructions on how to hook them up. Verify that you have a VSS sensor under the car. If you have cruise, you should. It's the sensor the speedo cable plugs into on the trans. If you don't have a VSS, you'll need to buy the VSS, a new speedo cable and a plug and run the wires into the car so you can hook them up to the new mass air computer. If your car has cruise control, you should be all set.

You want the 4-wire kit... CH-8611-F

As for the mass air sensor, i'd recommend doing this if you are still running 19's. 70mm is more than enough for most N/A combo's

Or you can pick up a Fox 55mm MAF for dirt cheap along with intake tubes.
