So helping a buddy out to convert is non running Dodge Coronet to a 350 TBI. I'm thinking on doing a clean wiring install so I'm gonna get a stock harness from a 7427 ECM and remove extra wires that won't be needed.

So far those are pins
F15 EGR Solenoid
E1 EGR
E15 EGR
B10 Cruise Control
F16 Canister Purge
B16
E6 SEL

And maybe
E12 if he goes no A/C
And
E13 cause it seems that it's just a brake switch for the EGR anyone can verify this? (My wiring diagram just shows it a as a brake switch that goes directly to the egr.
