2003 grand caravan

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

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.
