Hi you all, I'm having problems to get my courtesy lights running. During restoration I took it apart and now we forgot how it was! Does somebody have pictures how it should be put together again and if possible a wiring diagram. We are talking about a Chevy Malibu two doors of 1979. The junction box is under the dash on the drivers side. HELP!!

Hi Ribbedroof, Thanks for the picture but that is not what i'm looking for. But when you look at the picture you can see what i mean, it's a white nylon junction where they put some plug's!! Sorry for not so good english but i'm from the Netherlands Europe.

There is sometimes a jumper wire from the white-ish electrical bus to the fusebox, but I don't recall seeing one in a 79 Malibu before. More common on later cars/other car lines with more option content.

Assuming that for some reason your courtesy lamps are being run off the bus, there should be a jumper from the "BAT" terminal of fusebox to the bus

The bus that you can barely see in the picture is in a Malibu, but was swapped in from an '84 Monte Carlo SS, as I wired the car for power windows/locks when I had the dash out.

I'm thinking that the jumper is the heavy gauge black/orange stripe wire in front of the fusebox. I'm not where the car is right now or I would go look.

A lot of the 78-79 Chevrolets had an orange some light delay box under the left side of the dashboard. When this box fails you will not have any dome lights unless you manually turn them on with the headlight switch. I had seven different dome light delay boxes that I had pulled out of the junkyard over the years and they were all bad. What I ended up doing was jumpering the wires at the delay box. if you can wait until later on today, I'll take a peek under my dash to tell you exactly which wires to jumper because it's been several years since I did so
