Hi! I'm in the middle of an NA 1.6 to VVT engine swap. Being an EUDM engine my square-top intake manifold is a bit different than the previous ones mentioned. i.e., I'm lacking vacuum barbs and am in the desperate need for advice on where to route the FPR line and MAP line

https://www.miataturbo.net/attachmen...ine=1454166172

i have T-connectors, so i can tap into any existent line. i don't have any barb on the back end of the manifold. Only what is pictured

- orange: that fitting is currently plugged (spare barb for automatic transmission?). However I don't deem that an ideal location as it's right behind the throttle body
- green: that line used to run to the carbon canister I think. It will not be used (carbon canister delete)
- pink: no clue what that short line is for. Internal idle valve?
- yellow: same as pink

so where should i tap? shall i put a T-fitting between pink and yellow, and run that line to the FPR - and put in another T-fitting for the MAP sensor line?

On my VVT swap with a flat top I am running the vacuum line from the orange port. Seemed to work fine for the few minutes I had my car running.
