extra relay!
my 1987 K2500 4x4, 350, automatic has 2 relays up on the firewall, I know one is the fuel pump relay but I haven't found what the extra one goes to or what it is or was supposed to do, any body got an answer or just forget about it? thanks

Re: extra relay!
Hi bikernut,
I think it's a downshift relay for a TH400 transmission. Ray |

Re: extra relay!
nothing stops working when unplugged as it doesn't have any connector to plug into it, it is just there and I was wondering if I should be looking for some missing wires as my wiring diagram doesn't show it, but it is there and I have seen a few on both K1500's and K2500's with it and connected but that was a while back and didn't give it much thought until recently.

Re: extra relay!
