Centech w/ existing Explore swap

[Tiko433]

I have had my Explore swap running flawless for over a year. I’m the process of installing a Centech harness. I removed my original harness. I was careful to leave what I could of the Explore harness and label what I had to separate from the stock harness. I’m looking for tips from guys who may have gone this route. I got the dash harness installed and moved on to the passenger side to the battery. When I connected the battery and solenoid to confirm I was in the right track I connected the battery to see if it would start.
When I turned the key I noticed the fuel pump did not click on. I have a check engine light, it did not come on. I’m running the Explore 4G with a charge light and and volt gauge , they did not come on. Both those lights are supposed to turn on when the key is on then go off after started.
I really thought my Explore harness being a stand alone system and I connected every back to it It would be Ok.
So for you guys familiar a connecting a Centech to a Explore harness let me known
I talked to Gary the other day and he told me about some areas to check.
97 Explore
Coil packs
EFI guy harness
Explore 4G alt
Gear Reduction starter/ solenoid on stater .
I’m using the stock Bronco solenoid to start everything off.
Just a Not I have not finished the rest of the harness, meaning headlights/taillights I would not think it would effect what I’m troubleshooting now.
My fan, dash lights and wipers work so there is some good news

Main 12V wire from EFI Guy harness not hooked up to power.

Loss a Grnd wire somewhere?

Possible you lost a fuse(s) for EFI harness?

Thanks
Is the main 12V wire the one the goes behind the Ignition switch? I believe that wire should be connected to “key hot/start “ I will check my fuse block. Gary said I should see 12v in center wire on the coil pack plug when key is on , it’s not there so I think your right the computer is not even get power.
