[@vancedray7090]

I understand that congratulations are in order.

[@juandiegoortega457]

Where can i get the pin up for a OBS 95 or the pin up you used?

[@fuelinjectedduck2964]

Do you have any sources or videos on how to thin the 1990 TBI truck harnesses?

[@mcnealsgarage]

You can go to LS swap.com and get a good idea. They made alot of these trucks in different variants so it will be different

[@alphylopez702]

Yeah I know how to idk if you are confident enough in doing it you are

[@huey9114]

Why did you keep cruise control wiring won’t that not work with terminator

[@mcnealsgarage]

It has nothing to do with the terminator. The terminator won’t care. Take the 2 wires I mentioned, setup a speedo output wire from the terminator, connect the output and the 2 wires together. That gives you a working speedometer on your factory gauge cluster and cruise control.

How get abs light in ls pcm?

[@mcnealsgarage]

I think you have to leave all the ABS wires and connect them to the LS PCM wires for ABS. Not 100% certain because I didn’t, so might take some more research
