Well the 4 wires that come out of there are White, Red, Green, Black and then a all metal or mash that in cases them. The truck is a 84 and the motor I was told came form a 86.87.. I will add some better pic's to this. Sorry about how small the 1st ones was. It was the 1st time I have ever had to get a url to post a pic's on a site.
The colors are White, Green, Black, Red.. That come out of the Dizzy.. And I don't think it has a Vacuum Advance on it.. That is why I think i need a Dizzy out of a 83 or 84 but just not shore they will interchange.
