1986 odyssey, 4cyl fuel injection, overdrive button on shifter turns overdrive light on and off located on the dash but no power to overdrive solinoid, does it have a relay , if so where is it ? i have used a hot lead fron cigarett lighter to a on ,off switch to the solinoid on the tranny and now i have overdrive but sure would like to fix it as it was from the fractory, book says it has a relay and a temperature sensor, but i don't want to try tracing wires to find them, ooooh way tooo many wires
