[QUOTE="drmjf86, post: 1139042, member: 18583"] My bad, I found the fuse number being referenced by FJRCarShopGuy in my owner's manual (rather than the factory service manual) - the #12 fuse is the 3 Amp to the auxiliary DC jack in the storage compartment. The brown wire that I understand is the "absolutely" correct wire to connect the AVCC power feed wire to is fused by the #8, 15 Amp. The rationale for this being the "absolutely" correct wire to connect to is that the AVCC control logic compares this wire to the purple wire to "know" that the brakes have been applied. If the AVCC control was getting it's 12 volts from any switched source, then, in the unlikely event that the brake lights don't actually work - i.e., blown fuse or something - the cruise control would not disengage with the brakes because if the brake lights weren't working the purple wire never gets volts. If the AVCC control gets 12 volts from the hot side of the brake light circuit, it won't engage if the brake lights are dead because that circuit won't have any volts to give it. This was described as a designed-in safety measure and it makes sense to me. Has anyone used this "belts and suspenders" approach - that is, used the brown brake light fuse wire to connect the AVCC power feed? Mike [/QUOTE]
