what color and where can i find the wire for the interior dome light to hook up running board lights to come on when the remote is pressed to open the doors

recommendation use a relay wire a relay to engage when dome lights come on because your running board lights may demand to much power that the wiring for dome lights can support use a relay and separate battery power supply

seperate battery i mean run power wire from battery to terminal 30 on relay and running lights to 87 ground running lights to frame of vehicle. cut yellow w/ light blue strip one side to 85 other side to 86 . dome light on 85-86 engage relay power flows from 30 to 87 to lights ... 87a cap it off

thank you very much i already have the amber lights working off of the DRL and the signals and the hazards off of a relay i just need to hook up the remaining white wire for the courtesy lights ( which are white lights ) off of the dome wire
