Ignition Switch Wiring

[Hotrod1952]

I am using a wiring harness, ECM, & TBI engine out of a 1987 R20 in my 66 C20. I want to use the ignition switch from the 66 and integrate it into the wiring harness of the 87. I have looked at both diagrams and am a bit confused on a couple.


66 Switch----------Function------------87 Harness
Connector

Red----------------Battery + ------------Red - 2qty
Purple-------------Starter Solenoid------Purple
Pink---------------Distributor or ECM----Pink
Dark Green-------Ground- gauges?-----Tan/white - brake switch ground?
Brown/White-----Accy- Fuse box-------Brown and Orange?


Sound right???
