Remind me the routing for the CTIS harness?

[ramdough]

So, I just installed my winch/auxiliary harness into my dash…. Getting ready for my evaporator install.

does the CTIS harness route from under the dash in this hole from the center area?

Might need a new connector plug…..



looks corroded and burnt.

S looks burnt and U has corrosion.

I dont think it goes all the way under by the gas pedal. I think it turns toward the rear just before that, under the park and trailer air controls and comes out a hole in the side of the box below the park control. Then it goes around that front corner and right up to the side of the CTIS controller.

U is the speedometer input from the transmission, S is the overspeed signal to the dash light.

What does the CTIS controller side of the connector look like?

can you please Post a picture of where it comes out? My evaporator hopefully has the same hole.

FWIW. My old heater unit had a hole in the side right where my right knee is when driving (maybe lower). The wire came out the side panel near the lower rear corner of the unit, and ran around the corner to plug into the CTIS control.

The new A/C unit did not have the same hole, so I drilled one and installed a rubber grommet.

My evaporator does not have that one. Have to think about what I want to do here.
