Hello everyone,
Does anyone have a diagram for the body harness 98 connectors and 99-02 harness body harness? What I am doing is coveringt to a 02 PCM and repin harness work ok but my 98 harness is shot form spicing. I want to start fresh. And is anything should I need to know befor going this route?
Thanks in a advance!!

im doing the same thing my 98 harness was shot so i replaced it with a 2000 harness and a 2000 pcm with all of the 2000 sensors and now my cluster doesnt work at all the 98 cluster or the 2000 cluster i have.

if you still have your 98 harness you can remove the wires needed form there.
but I believe that you will need:
oil press
temp
speedo
rpm
fuel gauge
I will have to look up the pinouts for the pass side kick pannel they are in there, the 98 have 3 connectors the 99 have only 2.

you need to run the 98 sensors and use the 98 sensor connector. then run the extra wire to the pass kick pannel.
example, the 98 uses a 3 wire temp sensor, the 99 uses 2. the 3rd wire goes to the cluster.
Its going to be much easier and faster to just get a 98 harness and just repin the pcm connectors to the 99 pinout.

I would just use a 98 harness but I already have the 2000 harness installed so it would be more work then just adding a few wires to all of the sensors. I was wondering when I hook up my hptuners to my obdII i can see my tach and speedo so could i Just run a wire from the pcm to the obd connector and get my rpm to work that way.
