Fuel Injection Install - ECM Location
Guys - I'm starting a TBI install on my 78. I'll be using a 16197427 computer that I've tested and has good functionality. I am thinking of mounting the computer in the jack storage compartment and routing the wires thru the center console.
Earlier today I checked behind the glovebox, no space there unless I omit the liner. Don't want to do that if another opportunity exists.
Anyone have details and/or pictures?

This is the reason why I am going with an integral ECM on my rebuild.

Unless you bought an aftermarket harness you probably will need to extend the stock harness to reach the storage. What I did was install mine under the radio as I planned to go to a new radio anyway.

Did you route wires thru an existing hole there? I have plenty of harness material and planning to build mine from OEM components. I have a complete harness I used for a brief Megasquirt install on another vehicle, but think I'll start this one from scratch.
Any other install insights?

I also fitted a comms connector that sits just behind the lower part of the right dash pad. I plug my laptop into this for tuning.

Based off avatar pics, those with mounts behind glovebox (zwede, wabco40) have the map pocket style dash? Has anyone with the 78+ with a glovebox used that location?
Thanks for the input so far guys!

in '95 when I bought my '72, the wires for the L98 injection were run through the firewall, down in a crotch of the air ducts, below the wipers, and comes out just below and to the right of the HEI...so no good reason the wires could not neatly be run under the console and into the storage bins....my computer is of course behind the map pocket, you MAY try reduce the depth of the glove box liner....dunno if it worth the bother....
they may have changed the ducts around and so that firewall location may not work for you....

I bought an issue of the February 2006 Corvette Fever magazine where they did a similar TBI install on a 77. The picture showing there routing thru the firewall isn't very good (extreme closeup), looks like they might have gone thru next to the accelerator pivot point. Going to get under the car soon and check it out.
