I installed a prostart in a 2003 grand caravan about 2 weeks back which was previously in stalled in a ford taurus so it was pre programed and workes fine untill my wife pointed out the brake pedal did not shut off the starter.

In reviewing the wiring the wiring to the brake is corect but but I have been reading about resisters and relays needed for second accessary which is working fine with out, and 2k resister and relay at parking lights negitive triger.

The prostart has negitive pulse wire and lights work fine.

Is the wiring diagrams assuming a positive triger from the remote starter and do I need a second accessary wire for somthing

I don't think it's going to be a resistor issue.

---If you got the parking light resistor wrong, you wouldn't damage anything. The lights would just not come on at all with remote start, or you might get the headlights and/or fog lights coming on at the same time too.

---There is no accessory wire needed. There's a wire that's supposed to see 180 ohms through ground during start (it's the PURPLE / brown) but most 2003-2007 seem to work fine without it. I always hook it up anyway, though.

(By the way, the 2001-2002 would also work without the 180 ohm wire hooked up, but then there was a recall to reprogram the PCM at the dealer. Then all the cars came back and installers had to go in and connect the wire they didn't know about before.)

So, basically, it has to be a simple basic brake problem......

--Make sure brake lights on the van actually work.
--Make sure remote starter's brake input is connected to WHITE/ tan at the brake pedal switch.
--Put your wire tester to the little pin right where the wire enters the remote starter, and make sure you get positive when stepping on the brake.

It's got to be either the wrong wire in the car, bad connection, broken wire going into the remote starter, or maybe even a bad brake switch on the car. (PS: Chrysler brake switches do fail, and are cheap and usually in stock at the auto parts store.)

Changed out the remote starter and now brake switch works so must be somthing wrong with old unit.

In regards to the second ignition wire, I hooked it up to a relay powering through positive from 5th relay on the remote and negitive while running , with a dioad to isolate from the bypass, and now there is no power to accessorys like the heater . I also tried just grounding to frame with the same problem.

I wired 85 to ground 86 to positive 30 to ground and 87 to purple brown at ignition through a rab-180r--100 1/4w resister .I have never seen r refered to as ohm before but I was told it is the same as ohm and it tested the same.

Any sugestions would be appresiated thanks.

All done finaly wrong resistance at second ignition.
