R11 kickdown doesn't use the Packard or B-W relay. That's just for solenoid load.

For the coil, there are a set of contacts in the solenoid that are made when solenoid is engaged but circuit is not complete because of the kickdown switch. As soon as kickdown switch is activated, that coil circuit is completed while the relay simultaneously loses power and drops the solenoid power. With the solenoid dropping out just after the coil circuit is complete, the interrupt is only active for the few milliseconds it takes to drop torque and release the solenoid and open those contacts.

I wish the complete schematics were on that install page the company offers. They mention a tach could be added to that terminal but no mention of overdrive. With all the cautions about reversed polarity and hooking up things properly so as not to damage the unit, would like to know exactly how the OD is done. Using the original circuit, the electrical "noise" would be horrific to the electronic module so they must have a "clean" ground supplied thru the relay. Would be interesting to know what they did and if that relay uses any of the original circuitry for it's command. Might be useful if you have to troubleshoot something.
