Hey is their only one year great works for a 1989 S4 fuel injector harness? Does a 1990to 1995 work for it?

Nope 89 was it’s own animal. Best to rebuild your existing harness.

You can also get a new one from Kroon Wiring if you want to pay for a new one.

Our vendors offer them. Try, in no particular order, 928 International (RL: Mark Anderson), 928SRUS (RL: ROG100), and Greg Brown (RL: GregBBRD). Some have sourced the wire and connectors themselves, but the aggravation of getting the wire colors right and building/testing is more than the cost of a full premium harness from these folks. In my opinion anyway.

I d not think that air filter base is correct for 87. Beginning with LH-Jet cars in 85 the base has a hole for an air temp sensor. Earlier cars did not have hole/sensor.

Jason,
I'm not entirely sure why this was posted in this thread, but just FYI, the 84 Euros have a hole for an air temp sensor. And also, there is an upgrade for the sensor itself to a faster sensor that could make those engines that use the air temp sensor run more efficiently.

Only LH2.2 cars use the air temp sensor in the air box. All LH2.3 (S4 and up) use knock sensors instead.
