HELP!! Starter won't engage with key now!

[Hardwareman]

I just went over my entire wiring harness and put new thicker gauge cables going to the alternator and starter but now the starter will not engage with the key. Only when I jump the relay terminals on the firewall.

I've got good voltage going to the starter but I don't know where else to look. Can someone with experience in this area help me please? I'm trying to get back up on the road so I can go to work? Thank you.

Hold on a minute! I'm an idiot!

I forgot to plug in the wiring harness underneath the truck where it connects to both 02 sensors and another plug too! I don't know if that has anything to do with it but let me try that first......haha

Sorry to waste your time guys but I figured it out.

There were three wire connectors underneath the truck by the tranny bellhousing that I spaced on. Two of them were the oxygen sensors and I don't know what the last one was but it definitely was related becuase it's working now.

This site is awesome man!
