Thanks for the info, ithink i can put mine there is seams the smart thing to do but if it will fit on top of the heater that would be better, i have a new fuse box because i didnt think I was mech inclined to use the mustang harness and spent to much money on a painless harness but let me tell you it was easy and i was able to do it myself, couldnt aford it but me makes me feel better to do it myself, but it will fit in the glove box next to the other on thanks jason.
