I am going to be putting a 91 high port into a 98 Sentra SE. We are going to use the harness from the high port because one the car was bought without a motor and two the harness that was in there is hacked up a bit for my liking. Anyways. I am mainly concerned about the pugs that go under the dash on the ecu side. I need the diagrams of a 91 b13 and a 98 b14 to make jumper so it works. If anyone's got something that would be very appreciated.

That's a pretty big wiring pain in the ass. Save yourself a huge headache and swap the 98 intake manifold onto the 91 motor and buy a good, clean 98 harness.

it a high port motor the manifold bolts are different the a low port. I got a old b13 I can get any connectors out of because we are junking the shell because of the rust. I am up for a challenge anyways. If I have to make jumper I will or replace connectors. Its getting a DET this winter so If I can just use what I can between the cars I would like to.

Cool. I hear ya.

Yea I think it should work?

I'll trade you motors. I still got the complete motor and intake manifold from the '98. Trade that for the highport. I need 1 of those for my '92 G20.

Do u have a extra wiring harness? that one is missing some stuff and I thought u didnt get that motor running good?

Ok I will let you know

I got all of these diagrams for a 91 nx2000 from my buddys account at a dealership he works at. Hopefully they help.
