87 Chevy S10 - 2.8L fuel injected

I'm trying to help a friend install a gen in his 87 Chevy S10.
Anybody know anything bout these trucks?

1) Where do I inject the HHO supply line from the gen???

2) Which wire on the MAP sensor do I use to the enhancer?

Once I get those two info, I'll post install details for future installers.

ThX!

I put hho gas line pre or post air filter, I don't like hooking hho gens up to vacuum. The map signal wire is grn. By the looks of the picture the coil has a white burn spot on it, probably needs to be checked. Good luck.
