Front turn signals

Got the headlights wired and installed with your help, thanks.

Now to tackle the front turn signal lights. I have the ground figured out, easy. Now I need to figure out which connector on the combo turn/running light bulb to hook which wire to. The running light has a tandem wire that runs to the small marker light, but does it matter which terminal on the combo bulb it hooks up to?

Do you have a wiring diagram?

The gray wires are for the parking lamps, they feed the dimmer (longer) filament in the dual-filament lamps. The side-marker lights get their power from the same source.
The green/black and white/black wires are for the brighter (shorter) filaments in the dual-filament lamps.

Thanks, I do have schematics, but they don't show which terminal on the bulbs and the terminals aren't marked in the turn signals. If you look at the diagrams and take them literally, terminal 58 would be the outboard terminal on each of the turn signals. Obviously that can't be, or there would be left hand bulbs and right hand bulbs.

True. It's drawn like that to avoid as many crossed wires as possible on the diagram; sometimes the pictorial diagrams can be a little confusing because of that (for example, they show #1 & #4 spark plugs both on the same side) but most people still prefer them to the `73-up "current-track" diagrams which typically show the two filaments of a bulb in totally different places.
