I would check to see if you get power to the PCB. you could energize the pcb in that circuit and ground it and see if it lights. remember the headlight switch and dimmer
Yes it is. ](*,) The bundles going to the cluster seem intact where the 3 plugs (lights, pin connector and wipers) go into the cluster. Guessing something upstream may be hacked. The 4th pic is the plug for the light switch. I noticed one terminal by my index finger is empty (can see the blue tape showing through). But I did not find an obvious corresponding wire/terminal end... Not sure if that is by design or not?
Nope. Found it just like you see it when I pulled the cluster out. Have no idea what it's for. Amazingly the car starts & runs great despite the hack job. But being as anal/paranoid as I am, leaving it as is isn't an option. Just my luck one of the many "hanging" and wires will short out, and/or catch fire. But, such is the life of a gearhead and his project.
And another Big Thanks to all that have piped in with the great info/suggestions etc.
