i bought a blower box off ebay that was supposedly for my year car. i get it and none of the plugs are remotely close. i took the ac and heat out as it was drag car. now im making it a street car again.

i have many problems

!) rewiring the blower motor and resistor. problem is i dont know what plugs go to the blower motor and how to wire in the resistor. i plan on using spade connectors to wire them both, just need the assignments and which plugs.

2) vacuum diagram, the only one i can find is one that has the 5 vacuum lines on it. as you can see in my pics i originally had one that only had 3. i dont know what im missing here and which ones go where would be very helpful.

3) the wiring at the hvac controls, it looks like i cut them, but cant remember. there is a relay and the spades coming off. which wires go where?

4) do i need the piece under the dash on the right? and what is it for?

that pretty much sums it up. any help would be greatly appreciated

Re: hvac wiring
I noticed the connections are for a ac system are you putting AC back in or just a ac delete box for heat?

Its been awhile since I've seen a AC set up so bare with me

FIRST POST

first pic - those 2 lines are cut for sure and the other connects to the panel. There should be a spot that the 2 tabs/holes slide over mounts to

Second pic - is all the lines that go to the HVAC system for diverting the air coming in and go to the freash air vents

Third pic - no clue what your trying to show

SECOND POST

First pic - thats where the under dash HVAC ducting box goes to divert the air in. Do you have one as I dont see it in any of the pics at all?

Third pic is of the freesh air vent that one of the vac lines connects to

The last 2 posts are the right blower box for the car and the right plug ins but the harness you got for the HVAC doesnt look right at all as that harness should be on its own mainly.

Like I said I dont do AC but Ill try to help anyway I can

Re: hvac wiring
thanks for being the first lol, ac is going back in the car and i have all the stuff for that. yes i have the box that contains the heater core. there are 3 vacuum "*****" on that and the one under the dash. so thats 4 total. that would leave one to go to the manifold.

im really regretting tearing it all out
second, what do the two vacuum lines that are cut go to? thats the only one that fits on the controls. also would it be beneficial to buy a new hvac harness? rather than try to figure the mess out?

its fine, we are going into spring now, so im not too concerned at this point. i was thinkin about ditching it all and just going with a summit heater, so i dont have to deal with it. and the car has t-tops and windows lol. just thought it would be nice on humid days.
