I know it's a cheap way of doing a bypass, but I plan on wiring a relay and resistor(s) to bypass Passlock II.
My question is what is a good selection of resistors to buy so I'm preppared to do this install? And I assume the higher tolerance resistors are what I should get?

resistors and relays will do the trick fine. With PL2 you need to match the value as closely as possible, so some high tolerance resistors are preferable. They say that the pass lock will work with a value plus or minus 10% of what the car reads, but since resistor values change over time, and more so in cold weather, try to get it within 10 ohms. Any 1/4 watt resistors will be fine, just make sure to meter them before you put them in.

Radio Shack has like a massive quantity of resistors you can buy in a pack...I think it's around $10 for several hundred resistors in different impedance values. I don't think the tolerance will make that much difference.

Passlock 2,

cheapest way

forget the relay....once you get your measuremnt connect  the resistor(s) ass follows

cut the yellow wire (theft system) , connect the resistor to the yellow ecm side(leave the yellow key side alone)

and connnect the other end of the resistors to the black wire.

try starting your car by key, if it starts and your anti-theft does not stay lit....your good to go. If it stalls you have the wrong measurements , check the value of the resitors.

Testing is the key

Wow, quick response, thanks.
Any suggestion on what values to get? I'm not sure what ranges the Passlock II systems operate in since I've never done one of these before. (almost all of the immobilizing systems I've done have been the transponder-type)

Nevermind, the answer was just posted in the time it took me to type the last post!
So Slicksam, you just permanently disable the factory system all together?

ok to get the measurement.

I usually start the car , cut the yellow wire take the red lead from my multi meter connect it to the yellow KEY SIDE

and the black to the black wire near the yellow, write that number down, THEN  I switch the leads around to get another number,

eg.  first reading 8.09k        second reading 7.69k

I would use a 8k resistor  

that values are all different on every car.

yup...sorry to say , but there a pain in rear, especially the passlock 1

any passlock 1 or 2 , I don't bother screwing around...resistors and have a nice day.

I don't think that those cars will get stolen...no offence to any GM or chevy owners...I just hate that anti theft device

so you do a half-assed bypass job based on your own personal tastes??   wow, dont work on MY vehicle.....

GMC4x4Guy... do yourself a favour a go out and get a data bypass for your vehicle, something like the GMBP or 457G... there are only 4 wires to hook up, it takes 5 minutes and it reliably bypasses your Passlock circuit only during remote start......

so you do a half-assed bypass job based on your own personal tastes wow, dont work on MY vehicle.....  <--------buddy i was installing starters way before these modules came out.......I have seen ALOT OF TOWINGS being brought to me cause the customer is trying to start the car and it is stalling. And IT was not me who installed it. There are certain cars that I bypass it completly like cavalier, malibu and sunfire(older models). But there are certian GM cars that I do install the by pass on it.

I know FOR SURE that with my way, if the key starts by key.....It will always start by remote starter

and another thing........customers will try to cut the cost anywhere possible. quoted by GMC4X4 "I know it's a cheap way of doing a bypass"  I rest my case

Testing is the key
