rs 1000 in 2001 chevrolet silverado

Thanks another-kelly.

I've got some more time this week so I'm back at it.

H2/1 - RED / white wire - This wire is the input to the flashing parking light relay.  The connection of the this wire will determine the output polarity of the flashing light relay.  IF the vehicle has +12v switched parking lights, you don't need to connect this wire as it is already connected to a +12v source.  If the parking lights are ground switched, cut the wire and connect it to chassis ground.

H2/2 - white wire - (+12V 10A output) - connect this wire to the parking light wire coming from the headlight switch.  do not connect it to the dashboard lighting dimmer switch as the dimmer will be damaged.  The limitation of this wire is 10 amp max, do not exceed this limit or damage to the alarm and parking relay will result.

1) The way I understand this vehicle has +12v switched parking lights at the brown wire in the light blue plug at the BCM.  Can I connect the white wire to the brown wire at the BCM?  It shouldn't ever pull 10amps from there?

2) Since they are positive switched parking lights I suppose I leave the RED / white wire connected to the red wire and hook it up to a constant +12V.

3) Speaking of constant +12v, when I was connecting H1 to the ignition wires, I found only one thick red wire, I tested ti with a DMM and it is constant +12, but I need two, I did see a thin red wire and tested it and it also had +12v with the ignition off and key removed.  So is this the second +12v wire(the one with the red clip)?  I just wasn't sure because it was a smaller wire compared to the other one(with the green clip) and compared to the wire it connects to in H1.

4) Can I connect all the wires that need +12v all the time to the red ignition wires?  Probably to the bigger one?

Thanks

Thanks joch1314.

I did check the fat RED / white but I didn't get anything, I'll try agian tomorrow, maybe I misssed.

The reason I wondered about hooking the parking wire at the BCM is because I thought it might be easier and I wouldn't have to worry about how much current it draws but I suposse the switch is right where I am working and I could always use a fuse.

The brown wire will draw the same current whether or not you connect it at the BCM or the switch - I think the only reason it goes to the BCM is as a signal input for the "lights-on" reminder chimes and such. 

Unless your truck's got extra lighting (running boards, cab markers, etc.) or a trailer connector wired directly to that parking light circuit (I believe that '99-up Silverado has a separate fuse for the factory trailer wiring), you should be allright with the direct connection.

If it blows the fuse on the RED / white, you can always put in a relay for the parking lights.  The angry warning about relay/control module damage only applies to idiots who blow that 10A fuse and then replace it with a 20A instead of wiring in a relay - and you don't strike me as the type :-).

Also I agree with joch1314 on the RED / white at the harness being 12V constant.  Basically all GM vehicles with heavy gauge ign. switch wires have red and RED / white, or 2 separate red as their constant 12V feeds.
