90 Supra N/A positive batt cable

[doodah]

Okay guys this is a little embarrassing. I started rebuilding the motor in my 90 N/A MKIII
a little over 2 years ago. I am now down to vacuum hoses and my positive battery cable installation. The positive cable is consisted of two seperate cables. On one end is obviously
the positive post connecter, on the same end is a large flat spade connector covered by a large red plastic cover, the other ends are flat spade connectors. What is throwing me is that the two leads to the starter come out of the wiring harness. I have looked at the manual and other schematics but cannot find the proper method of installation. I promised my son on his 16 birthday he could have this car. He just turned 18 and has been very patient. I am ready to eat crow if someone could help me .

Thankyou for any replies.
