What’s up Daniel? Looks like you’re moving closer to road worthiness! AIR system is all there, I took an “assemble” pic when I removed it to aid in reassembly. This is as if you’re looking from the front left of the car:

hey guys got a little situation here finally got all the parts I need for my emissions here in Arizona my problem is I'm running 91 exhaust manifolds with a 91 diverter for the air system now I've got some 86 exhaust manifolds that I'm going to be getting off this guy because I noticed that the 90 ones one side faces forward and one side faces back as far as the little nipples or valves or whatever they are and for an 86 they're both supposed to be facing backward towards the cockpit area so my question is can I use a 91 1990 to whatever air diverter instead of one for an 86 I noticed that the 86 the little connectors are round and the ones for 90 through 92 or kind of a D shape their squarish so as long as I get the pigtails for the other ones would I be able to use them is there a difference in voltage amperage anything like that or can I just put them on and use ok
