Hi guys, I need a little tech help here... I got a little overzealous repinning wires in my rush to rebuild the connector for J5 on the PPB. I pulled out the entire PPB to redo the header pins, which turned out very nicely, but now I am stuck with a mess of wires that I've repinned but don't know which order to reinsert in the new connector. Stupid move not to label them, I know. Let that be a lesson learned. The only pics I have for reference are a couple of the toasted "before" pictures.

What's really throwing me is - Even though I have the manual and schematic of the wiring, I don't know how to differentiate between the two sets of wires when there are two of each color. Is there a simple way to tell which is which? They're all in the same bundle of wiring, so I am totally lost. Also, why do I have nine separate wires instead of only 8? Is one of these supposed to be looped?

Thanks for any help you can offer.

This is the map of J5 I found in an archived RGP thread:

Pin 9 wht/vio Playfield
pin 8 key
pin 7 wht/grn back box door
pin 6 wht/yel plfd & coin door
pin 5 wht/brn back box door

pin 4 wht/vio
pin 3 wht/grn
pin 2 wht/yel
pin 1 wht/brn all go to PS connector 8

pin 1 to 4 on PPB side is 6.3 vac IN
pin 5 to 9 on PPB side is Fused 6.3 vac out

Just an update, I think stangbat helped me get the information I needed for my connector issue. I will give it another go tonight using his suggestions and report back.

Edit: Yes! I got my connector problem solved thanks to stangbat's help, and the game is better than ever. I'm definitely going to be more careful this weekend when I redo the header pins and connectors on the power supply board.

Tomorrow I might take a picture of the wiring to J5 while I have the backbox open, since it seems to be a common point of failure and I couldn't find what I was looking for online. Hopefully it might be useful to someone else in the same situation as myself.

Quoted from RussMyers:
Here's what I do to avoid this:
I get the pile of trifurcon pins, flush cutter, wire stripper, new connector and crimper ready.
I put the key pin in the new connector, and then starting with one end (Pin 1), I cut each old wire, strip, crimp, and then insert each wire into the new connector as I go, one wire complete and inserted at a time. Then, when done, I hold the old connector up to the new one to double-check.
Almost impossible to eff it up that way.

Thanks Russ, that's a really good idea that I'll keep in mind for the future! Between the excitement of wanting to dive right in despite my naiveté about rebuilding connectors and the fact that the original was so burnt that it literally crumbled and snapped in half in my fingers, I just lost track of where things were supposed to go. I got it sorted out though (largely thanks to stangbat) and learned a lot in the process!

Quoted from Darscot:
What are the original colors of the scoop lights? My bunker has green on top blue on the bottom but control room and power shed are green on top yellow on the bottom, is this right?

That's how they are on mine and most all of the other ones I've seen, including the pics on ipdb - pretty sure that's even how they are on the flyer photo. However, the manual doesn't specify, so I can't say with 100% certainty.
