Altenator won't plug in

[jeff l]

I put a 1990 350 into a 1986 truck every thing will plug in but my altenator. The 1990 has 4 or 5 pins and my truck has only 2.

I tried to find another year that mounted the same but still had 2 pins.

I have the plug for the 1990 but it has one small brown wire and one small red

the 1986 coming out of the truck has one small brown and a lot bigger red---I am thinking about wire tieing the reds together and hope for the best

Any suggestions would be appreciated

Im sure it will work just fine if you tie them together

you can actually get a adapter connector that will convert it, but yeah, just match the colors and it will work

8078 or 8077 is the number do you have a gauge or not dont just tie them together that alternator needs a resistor to work right

or the resistance of a bulb, which these trucks have

I put them together and the batt keeps goining dead. found out that the Alt made a slight hum ; and was draining the batt

does your truck have a gauge or light? if it has a light than you might tie them together if it has a gauge you need that resistor
