Yes. The factory circuit is intact in the rest position.

Doing this right now.. Locks.. Light Blue and Dark Blue in Driver's kick.. There are about 5 of each color.. I tested all of them.. One set tests around 6V at rest but does not change when I hit the lock / unlock buttons..
All the others don't test any V at rest.. WTH?!

Also, do these require a tach hookup? I can't seem to find the injectors.. It looks like the Intake is covering them..

Just tested the resistor value.. If it had 1761 that means 1761 ohms, right? What commonly sold resistor value would work for that?
I just found that I had a 1870 one but is that close enough? If I try it and it's not will it jack stuff up or just not start?

you can combine resistors to obtain that number, if you put the resistors inline (end to end) you add the numbers to reach the value, if you put them together side by side the number is cut in half( i.e. if you took 2 of your 1870's and put them end to end youd have 3740 give or take a point if you twisted them together side by side youd have 935 ohms) try to get as close as physically possible to your number needed, also the door locks are in the harness somewhat inside the kick panels metal wall going into the door boot

Thanks for the reply.. I can't find the locks anywhere.. I'm in that boot boot in the kick panel but like I said there are like 5 blue and 5 light blue.. I tested ALL of them and only two test with voltage at rest but they don't move (stay at 6.3V) when I hit the lock / unlock..
Thanks for the tip on the relays.. So if I would get the value wrong somehow would that jack anything up?

if your too far off( they say you have 10% but i never want to push it that close) then when you tried to remote start it you would send a wrong code thereby not enabling it to start, and after a couple attempts would lock the vehicle out of even starting with the key till you reset the system(long key on process)but less than 10 % difference would be ok but i wouldnt trust 10% for too long(therfore your 1761 could range fromjust under 1600 to1930, but again get as close to 1761 as possible and i prefer to use only 2 resistors at most to achieve this )and door locks are there harness is inside metal of kick panel wall and rest at ground and show 12 volts when switch is used

Ok. I got a 1500 and a 249 so that should be close enough..
I thought (-) locks rested at 12V and then went to ground when pressed?
And does this vehicle need a tach hooked up? If so, where do I find it? I can't see the injectors!

yea 1749 is close enough, just wire them end to end and make sure they are secured with somehting taped to them(i use a pice of heavy zip tie) to strengthen them so as not easy to break ( as they are fragile) and sorry i was dislexic yes locks show 12 volts at rest and go to ground when switch used,(if i remember correctly reach hand inside hole in metal wall of kick panel to reach door boot harness) and no tach is needed as this truck has gm smart stART circuit( you could remove cover to get at injectors but ive never done this on colorado/canyon or h3, same vehicle) and you can set crank time to longest setting with no worries as vehicle will only crank as long as it wants no matter how long your starter does
