There's no resistors or anything in the connector, just the wires. Rewired this over 20 times, it breaks after about 20 to 45 minutes of run. The rotor in the distributor slices through the wires and you're screwed, it's a royal pain in the ***. I eneded up buying an 85 SPG distributor (I have a 93 C900T vert) and as long as you have the connector from the 85 (or any earlier year) just solder the wires into place and you're good to go!
For older C900 distributor's to new wiring:
Red from Older dirstributor wire goes to the black of the new wiring.
The other two, green and black, match up perfectly.
I would suggest just buying a remanned one of an older distributor on eBay, I got mine for $35 practically brand new, when the newer plug styles are almost $200 bucks!
