2008 express van, remote start

These vans are like the new designed full size trucks. You need a module to integrate the starter circuit and the transponder circuit. I use the XK06-PKG9 from Trilogix. It will take care of most of the wiring you need.sparky

is there 2 ignition wires?  which are they?

There is only one ignition wire but there are 2 pink wires. Only one is the ignition and the other is for the Passlock system. Get your hands on a module that will interface with GM's hybrid Passlock II/transponder system. Without a module, the truck won't start.sparky

just like all new gms, starter wire is not needed, just ign, accessory, power,ground,brakepedal shutdown,park lites,and a coded key in a universal bypass(dei 556u, or audoivox astcbm) truck will start when ign and accessory come on, accessory drops (while ignition stays)bcm then tells vehicle to crank have not done a new van but have done a ton of new trucks and cobalts and this way worls great(rumor is that this will store hidden codes but it will throw no lights and i scanned one a week after i installeditthis way and no codesfound so maybe it will store hidden codes after a while but i work at a gm store and have had no issues)

just use a xk06 and a xk01 very easy install.

well i did the whole now start wire thing on a 2007 trail blazer on accident. the vin said that it was an 06, but the wiring was 07 so i didnt have the starter wire hooked up. remote start worked perfect, but it threw two transmission codes.

The brake wire is @ BCM brown connector white wire.
