wiper motor problems

[syntech]

hey people, just have a quick question about the wipers on my 79,
when i got the truck the wipers didnt work, and still dont work, but what it looks like to me is that who ever had the tuck before me, downgraded the trucks wipers to one from a early 70's truck b/c it dosent have a delay, and its just has two speeds, now the motor does work for a mintue but then it just stop's, so i decide to go back the stock one, i do have the new motor, and the one problem is i dont have the oem wire harness for it and i cant figure out, what connection's need to go where on the motor, so i was just wondering if someone out there could take a picture of the motor hooked up on the truck and tell me what color wire's go where.thanks josh
