Harness routing with Vintage Air

[Thumpuppet]

I am doing an LS (LQ4) into a '71 GMC. I already have my BP harness and am planning to put the PCM under the dash. I have ordered my VA kit, but it's still about 5 weeks from delivery. In the meantime, I want to install my harness but don't want to send it through the firewall where the VA kit will be.

Can someone please post an interior picture to show the VA mounted so I get an idea of where I can (or more importantly cannot) put my harness?

Thanks!
