I have a 1980 4x4 with a 20r and GM hei module conversion. I'm not getting power on the wire that goes to the module from the ignition switch. I downloaded the fsm and don't see anything on the diagrams that showes the path from the ignition switch to the igniter. I'm trying to find out if there are any components between the switch and the igniter or color coding or any advice to try to troubleshoot this. Thanks

 

Here is a diagram that you can use to troubleshoot the wiring . Hope it helps

 

Thanks, that's how everything is wired up. I'm not getting power from the ignition switch here. I’m trying to find out if they're are any other connections between the ignition switch and where it connects there.

 

If you PM me here, as I have a good wiring diagram for 81 Toyota truck that I can send you. Then you can continuity checks

 

Sent, thanks

 

Please post diagrams in the open so the next person who stumbles on the thread in a couple years can fix theirs as well.

 

Any update? I think I might be having a similar issue

 

are those photos from the manual ?

 

 

The pics above were found on Google and match my wiring. I’m still in my restomod process, but that how I wired it
I would do continuity checks from point to point to verify your wiring is correct
