Batboard

I've searched the site with little luck on the following questions...

First off I'm planning on installing stobes in the front turn signals, rear brake and reverse lights with LEDS behind the grill and a Whelen siren.

Looking at the space under the rear seat rules that out as a location for the electronics. What is the best place for this stuff? Under the pass seat or in the trunk under the floor?

What is the best way to get wires into the cabin through the firewall?
Are there any tricks to getting the turn signals out?
What is the best siren mounting spot?
And finally, What color are the horn ring circuit wires and what is the best place to pick them up?

How install friendly is the Trailblazer?

Thanks for the help, I know this is a lot to ask but I'd appreciate any help and or opinion you may offer.

I've a 2002 TB with a Vector, 4 corner strobes, wigwags, rear halogens, remote siren. I put the strobe pack under the rear passenger seat (yes, there is room). I have a Kenwood TK-730G transciever unit under the front passenger seat, and under the driver's seat I have the Whelen Alpha siren box. To get the front light stuff out you have to pop the bow-tie chrome thingy off, just pay attn to where the clips are and pull appropriately. The rear lights come out with the two screws on each ass'y. I ran my wiring through the wiring harness hole IFO the drivers left foot rest up towards the top. Just made another hole in the seal and fed them through, sealed with some silicone for some insurance. Hmm for the siren speaker I have the CPI SUV-type speaker designed to be mounted under the bumper, I have mine mounted to some bracket under the bumper just behind the driver's side fog light. I didn't wire the Tap-II horn ring stuff in. Decided not to get all complicated, but that someone else here may know about that.

The TB isn't too bad, cars are much worse. Just depends on how diligent you are and how much you want it to look neat. Hope some of this helps.

The area under the rear seat has a power distribution point and fuse panel and the jack and tire iron. The rear floor on the pass side is uneven and has a wiring harness under it. Do you have any pictures you can e-mail me?

I have a 2004 TrailBlazer i will send you pics of all my lights and install work plus video.... If you would like...

post it here please...
