I am putting a 89 cab on a 78 k10 frame with a 350 sb everything fits really nice when you can pick where your cab mounts just having a little troube trying to get stock gauges to work i have already found my reverse and distributer and efi wires in the cab harness to engine harness plugs which are in the attached pictures i am still trying to figure out what wires are for the tach oil pressure and coolant temp. I already have after market gauges for oil pressure and coolant temp but i would like to try and make the stock gauges still work. i have the oil pressure and coolant temp sensors out of the stock toyota engine. The truck was a 89 extended cab sr5 4wd 3L pickup if someone would be able to identify the tach oil pressure and coolant temp wires that would be awesome 👌

This is the project

 

Theres a engine swap forum somewhere on here i think. Someone there might know.

Truck looks very capable!
