PCM Mounting Location for LS Swaps?

[NorCalAnthony]

Like the title says, looking for ideas or examples for where folks are putting the computers on their swaps. Posted the same question in the LSx Swaps forum on here but didn't get much feedback. Tried doing some searching and saw a bunch of stuff for the 67-72 trucks but hardly anything for the 73-87's...

Reason I ask is I'm getting everything together to swap a LQ9/4L80E/NP241 in to my 84 K5 Blazer along with a Vintage Air unit and wanted nail down the PCM location for when Speartech starts making my harness. I was looking under the dash and couldn't see enough open real estate on the driver's side to mount it up under there and VA unit requires modifying the glove box to fit so I don't think I can put it in or behind there on the passenger side either. I'm thinking it's going to have to go in the engine bay, most likely on the driver's side fender/wheel well area to keep the harness lengths to a minimum, but wanted to see what others have done before. Thanks in advance.
