FiTech EFI system

For the people not running headers, where would the ideal location be on the o2 sensor? Close to the manifolds on the vertical run of the pipe or farther down to the horizontal run of the exhaust?
And on another note.. if the dist was originally ran through a coolant temp vacuum switch, should that be bypassed or run in series with the switch. This is on the base model fitech that does not control timing.

I'd personally get it as close to the horizontal section as possible and make sure it's mounted off the horizon as indicated in the instructions. You can however run it in either location if needed (we have had a few customers who due to space limitations have had to mount them in a primary tube, or vertically) mounting it further down stream just gives it some extra time to blend/burn if you will.

on the distributor note...I can't imagine or picture a distributor being wired into a temp switch....am i reading that right? If it's a stock style distributor you're more than likely going to experience tach signal issues. even with a 400 unit.
almost every one of these i sell gets a distributor. HERE--->
