OK shove gear to neutral, feed from your 12volt constant source to the ignition, then fed from ignition to starter by flashing across. One of those two will start the car if it takes both, wire as follows. Your remote start starter output, feed from that to relay 86, ground to relay 85, constant 12V+ fused at 30amps to 30 and second starter wire from 87.
You might have only 1 ignition wire, there's no reason why not.

hi , thanks for that post but i had already looked that up on the forum the problem is that my wiring coe doesnt match all those colours , howie suggested flashing the ignitiion, but when i went to do it i bottled out(sorry howie) my wires and the readings i get are below if any geniuses out there can identify them it would be a great help . the general consensus is that theBLACK/ white wire is the starter but the BROWN / red behaves almost the same

i traced the ignition wires further down the harness to another plug and found that the wires on the other side of that are "by the book" so i can only presume the ignition barrel was changed at some time . there is a brown and red wire going to a black and white wire and a black and white wire going to a second identical black and white wire , so in essence there are two starter wires coming from the ignition switch!go figure !

anyway i should be able to sort it all out tomorrow evening but in the back of my mind i will always wonder why the two different coloured wires connect to two smaller diameter wires of the same colour, in other words why does start require two wires , any suggestions would be useful , not for the install but for my own curiosity

i am currently installing my new alarm (yes howie , still doing it ), this is a picture of the supposed starter kill relay supplied with the alarm with their colour coding labelled . i have looked at your database and cant match this method of wiring with any of the examples given . i  presume that i still have to cut the starter wire and wire as usual or is this a different way of doing it . any suggestions or explanations gratefully received .

The white yellow and orange are correct, red goes to starter (starter side ) and joined to the remote start's starter output. yellow is joined to the ignition and remote start's ignition output. Orange is the r/s alarm's GWA wire, i.e ground when armed. Ignore the blue, you don't have a 2nd ignition also at the ignition lead, don't wire up the brown or BROWN / red.
