DynaSpark Vent tube routing

I am cross posting this from the Ignition section since it actually fits in both.

I just upgraded to the DynaSpark since my Opti crapped out a couple weeks ago. It looks great, but wish they would of sent me some paper work with the thing. That being said, how do you route the vent/vac lines??

I am sure I could search around and figure it all out, but trying to get the car back together quick so I can get it outta the shop.

Thanks

On a stock vented setup, the hoses travel from the driver side of the intake manifold, down past the coil to the optispark. Pretty much a straight shot.

On your 94 manifold on the driver side, there is a plug. You'll need the fitting for the intake manifold (or use the EGR nipple if you have it deleted) for the source of the vacuum. The other line goes from the optispark to the intake elbow (or anywhere after the MAF).

I don't have a plugged hole on the drivers side of my 94. I just put a "tee" in the line for the EGR vacuum:
