I have some questions about my truck, I have a 1997 GMC K2500 first off does anyone know what the HP/TRQ is for the 350 under the hood? the truck is bone stock right now.
Second and this is really annoying is there any way to get the hazard flashers to keep flashing even when the brakes are applied ?
Since the flashers and the brake lights use the same bulb there is really only one way to do it. You would have to wire in a relay on the brake light lead. Jumper off the output side of the flasher switch and wire it to the coil of the relay and run the brake light wire (white wire on pedal) through the normally closed contacts on the relay. So with the flashers off, the brake light wire will run through the relay with no problem and work as usual but when you turn the flashers on it heats up the coil in the relay and that opens the contacts so when you push the brake pedal, the signal can't get through and poof, no brake lights when flashers are working.
