90-92 guys: Where is MAP sensor
Hello my speed density friends, I'm converting my MAF car to MAP and I'm wondering where the vacuum source for the MAP sensor comes from.

If anyone has a pic of the mounting of the MAP sensor, that would be awesome!!

On my 90, it's a small black unit attached to the passenger's side of the plenum with 1 bolt. The vacuum line runs underneath the plenum. Sorry, no pics, I'm at work.

I have no good pictures but on my 92, as Synapsis said, it's attached to the pass rear of the plenum with one 10mm bolt. The vacuum source is a nipple on the plenum by the fpr plenum nipple.

Just mount it to the firewall and tee into the vacuum line for the
fuel regulator.

That's what I was thinking swapmaster. There will be a nice empty spot from where my MAF relays were.

You need to keep the hose as short as possible to prevent delayed reactions from the ECM
