Thread: No cruise control or interior lights, fuses good, possibly wiring.

Interior lighting, possibly cruise likely both go through the bcm

It doesn't appear that any wiring has been added or tapped in to. Everything looks OEM except for that jumper wire in the fuse box between brake light fuse and HVAC high fuse that makes my OBD port, brake lights, and interior lights work. I don't know why they don't work without that jumper. If I remove that jumper I get intermittent OBD port and brake lights, and no interior lights at all.

The pink and brown wires that lead up to the CC box appear to be cut but I don't know where they led to under the dash. They are bundled with the brake light switch wiring, but there is nothing in that area that looks like it is missing two wires. If I can figure out where these go I'm sure the cruise control would work. One theory I have is that they originally went to the brake light switch, but a previous owner swapped the switch out with one that doesn't have a spot for those two wires. I thought of this because that brake light switch is very loose like it has been messed with. Without seeing another car like this, or having someone tell me where those wires go, I'm not sure I'll be able to sort this out easily. Haynes diagram for CC definitely did not help.
