On my 1987 Gl wagon the heat is conntrolled by a vacuum connection on the engine.Now that I have swapped in a ej22 I don't have alot of vacuum lines I can tap into.I found one however.Its comes off the top of the throttlebody on a 90 ej22.Can I T into that to make my heater work?I am going on a big wheeling trip with numerous rigs(I can get stuck all I want!!!) It just rained yesterday and through the night so its a perfect time to be out wheeling.Anyway I need the defroster working so my windows don't fog up with the windows closed.

Thanks in advance.

YOU also have a vacume resivoir. You can tape any vacume line. If you are worried about it you can also get a vacume pump. I do beleive that that year used them for the cruise control?

In case your '90 2.2 L is like my '96 2.2 L, I have a vac tap (pluged) on the intake manifold leading to n° 3 and 4 cylinders.
