right now i do not have a speedometer in my truck. the one in there is broke. i am wanting to do a custom gauge set with sutometer phantom gauges. my question is how do i go about hooking up an a speedometer. i want it to be correct with my gears(5.29s). my truck is an 89 toyota. it has a cable driven speedometer. anyone know how to make it work and have it be correct.

thanks
