Shop recommendation

[61squire]

Greetings, back again. I'm looking for a shop that works on Mustangs. I swapped out a 2014 Coyote and 6r80 tranny into my 1961 Ford Country Squire. I used an aftermarket US Shift ECU and harness. Now I want to change that out to a PBH ECU and harness listed here. CONTROL PACK - 2011-2014 COYOTE 5.0L 4V MANUAL TRANS WITH SPEED DIAL.

Got any recommendations? Much appreciated. I am in northern California. Thanks, Deane
