Overhead console in a 1999 that never had one?

[slim724]

Like the title states, I'm trying to install a overhead console in a 1999 that never had one and I just can't figure out the wiring, the small pigtail for the lights aren't a problem but the larger pigtail is, it has pink, black, dark green, purple/whitestripe, grey, and light green/blackstripe wires, of which none of those color wires are running in my existing harness by my dome light, can it be done without having to run a ton of wiring?

What year is the console? I installed one in my 91 that was from a 95. Be advised that if it's the newer type that has the Econ display it may not work on your van.

How do I tell what year it is from? it has the US/MET, and ON/OFF buttons, also has 3 latching compartments, 4 directional spotlights 2 front and 2 rear, and one square domelight, it has a part# V78959 TL-6512
S.A.E G.M.P P.P.E .009-P.P.E.

Tried finding the part #'s online but didn't find anything that matched, and unfortunately the pick n pull yard was closing as I was pulling the console, and I was basically escorted out, went back 2 days later and of course the van I pulled it from was gone, So I couldn't check what year it was, I couldn't believe it was gone since there was a ton of good parts still left on it! and the 3 gutted older astro/safari's Junkers were still left there with basically nothing left on them, go figure???

That sounds just like the overhead that's in my '96
