Where to mount ECM for TBI Harness

[Clinscott]

So I have a 75 K10 that I will be putting a late 90's vortec 5.7 engine in. I bought an aftermarket TBI Harness from Fuel Injection Connection and am at a loss of where to put a hole to put the ECM in the cab. I would like it behind the glove box. I have a reman ECM without a ECM mount. Any suggestions on how to mount. I hope someone can share some pics and an explanation on where they cut and what size grommet they used to seal the hole. Thanks in advance

I would put it where the factory put it, in a bracket above the AC.  All 81-87(91) trucks had this for the ESC and ECM.  It uses the same mount.

The guy I bought my truck from did the same engine swap and ... wait for it ... just put the ECM loose sitting IN the glove box.
