i need help.. i have a obd0 si harness and a obd0 dx harness. i need to know which harness is better to convert... i herd that si harness might short the fuses because the wiring does not match up.. is this true? if i do use the dx harness i need to know what to re-wire.. it would help if i can get a graph... so if u have the knowledge please share.

Good luck, I have to help my friend do this on his 90 std in a bit so this will be a learning process for myself as well.

 

Use whatever harness comes in the car you are working on.

Just add wires where necessary. It's easier than switching out the whole harness.

I recently did a dpfi to mpfi and OBD0 to OBD1 conversion in my 90 STD. All I did was follow the directions that I found through searching and it started right up with no check engine lights.

It's pretty easy, just take your time and follow the directions closely.
