Cruise Control ?

[Tony LEE]

"The relay was close enough to the Rostra Control module to trigger the module causing it to turn on. Problem solved by adding a diode across the coil terminals (85 & 86) on the relay.  Jack"

Yes, it's always been good practice to add a resistor or diode across coils. Stops a lot of sparking at the switch contacts and reduces EMI.

Having the cruise control is good - I can practice my tap dancing moves while cruising down the highway.
