hey "slater442w30" i saw you posted that you added ac to your 89 back in an 07 post and i did similar ac add to my 1989 xcab pickup 22re... ac works great will freeze you out of the truck but my problem is it really bogs the truck down when applying the brakes the rpms drop almost to where the truck shuts off... did you run into a similar problem? thanks

Yes, change the center of the heater box, the rest of the dash vents are the same, add the switch to the heater panel and hook all the wiring up, should all go in pretty easily.

Hello,

Reading through old forums I saw that you added factory air conditioning to an 89 4runner. I'm about to try to add it to my 86. I think I've got the under the hood stuff, but I'm a little confused about under the dash. Hoping you could shed some light on the subject. I've been told I have to completely change out all the duct work, but your post sounds like all you've done is add the cooling box. No need to swap heater box? Keep same vent ducts? I'm pretty lost here, so any help is much appreciated.

Thanks.
