I had this Upgrade cooling fan Relay for my 1986 Vett for a while now so it is time to install it.

But It did not come with any wiring schematic for the old or new how to rewire it to the new plug.

I looked at my Chilton But iy dont tell me nothing.

What wire what in the car as in color.

I know on the New relay #85 for the swicth, #30 for the Battey, #86 is Ground, And #87 is for the Component.

But which which from the OEM relay.

HELP.
 
Thank You for the Info.

Red is fan power ;30
Black/red is to fan; 87

85 and 86 get blue ( relay power) and
green (relay control )
Doesn't matter which is on which terminal ,
