Dennis - the resistor on the wiring diagram is the ignition resistor that's mounted on the firewall - all ya need is to tap off the brown end of that resistor w/ a fuse holder and bob's yer uncle - or was it ralph?
coil, starter, start sw and gauges don't change from what they are w/o the OD - notice the bottom left corner {OD relay} goes to "BAT" which just means hot/power; other side goes to {kickdown sw}, which goes to ign2 by way of coil, and to the trans {solenoid}
ties it all together - keep it simple!
Bill
oh yeah - don't know about the resistor for the radio, but it's to keep ign from makin static - actually now that I think of it, isn't it a capacitor?
