Hey Snake,
I don't know what your manual is showing, but if you have the GM column and the CR harness, everything should just plug together. Make sure you have the steering column pigtail harnesses. They should connect for wipers, ignition, and lights without any mods. I can't remember for sure but I think I had to run my own power supply wire to the wiper motor from the factory harness. As far as your red light. You should have a black wire #190 ground and a white wire (can't remember the number) from the dash harness That hooks up to it. If you put an adjustable proportioning valve on the car, that light will be useless. At least it is on mine. Hope this info helps, if you have any questions I may be able to help with write back or email me at

Good luck
