Need help with 95 tahoe ignition diagram



Hi everyone long time lurker here, im building a special project using my 95 tahoe i have owned since new. I am transferring the full drivetrain to my 66, i have my reasons (the body turned to swiss cheese) please do not get mad. I would like to find a detailed diagram of the ignition harness, my goal it to splice the old chevy ignition to the new harness but i noticed there are extra wires. A quick internet search and i didn't turn up anything. Any help would be appreciated Im running a 1995 tahoe 5.7l with 1999 4l603 2wd trans with full harness from the 1995. Attachments
