'86-'13 swap questions

[rodstored-72]

Well I have gone through each of the "X" connectors that attach to the bottom of the factory underhood fuse box. It look like 2-3 of the connectors are probably not going to be needed. One has the “ign-1” wires and the “ign-3” wires. My thought is to connect the corresponding “X” conn. wires to the OG corresponding truck wires coming out of the truck firewall? … thoughts?

I am STILL trying to find info. On the connector that I posted above, my local chevy parts house is not to forthcoming with assistance. I have been told that libraries can carry service manuals, but I am not sure?
I know I am close, once the wiring is figured THEN you will see a big improvement on the build!!
