Problems with DIY Exh Brake/EBPV?
Ok so I decided I wanted to try the DIY exhaust brake method before buying a $1,000 aftermarket unit.
I unplugged the connector from the compressor housing and cut it from the factory harness about 3-4" back from the plug. I ran the colored wire straight to a battery with an in line fuse, and I ran the black wire in the cab to a 2 speed style push pull switch. The valve will function with the switch in the on position and the truck idling, but when I'm going down the road and attempt to use it there is obviously no braking power what so ever. I've tried it unloaded and today with my 43' car trailer with a single Toyota SUV on it. At 2500 rpm's I'm getting no braking assistance.
My friend took me for a short ride in his 95 this afternoon, and even unloaded in his truck you can definitely feel when the valve closes and starts braking.
Any idea's or suggestions on what to do? Should I have ran the hot to the switch instead of the ground?
