8.4" Radio Upgrade Long HVAC Harness install Picture heavy.

I completed the RA4 8.4NA Radio upgrade from the RA1 a while back , originally I used a short conversion harness I purchased from getupkid.

I wasn't well versed in the upgrade at the time and shortly after I completed the complete install I learned of the Long harness & the factory hvac module Location , every since I've wanted to mount the hvac module in its proper location .
The short harness limits you to basically laying it on the plastic shelf behind the bezel and just below the radio , this rattles when turning quickly or going over rough terrain. I wrapped mine in large rubber bands. This fixed the rattle issue but I still wanted to install it in its factory location .

There's nothing wrong with the short conversion harness I purchased from getupkid, it's worked for me for a year or so .
I got my hands on a long conversion harness from a member here Mpgrimm2 / M2mods that was very nicely made . Lots of attention to detail with the harness. Wrapped in a slick braided sleeving and heat shrinked on the ends, different color wires and all the wires individually marked with numbers , and obviously the proper oem type connectors on the ends .
To say the least , I'm very impressed with their harness .

Perfect length for the install.

Step # 1 disconnect the Neg lead from the battery . 10 mm .

Next remove 2ea screws here T20 bit.

Now take a firm grip here and pull straight back to relieve all the push clips.
You may want to use two hands .

With the short harness , this is my hvac module wrapped in large rubber bands.

Notice the giant difference in the harnesses.

This is the factory location (all this info can be found in the beginning posts here )

1st pic is the two key slotted holes for the install of the module, 2nd pic is the module installed .

And this is how I routed the harness.

Plug everything back up.

Reconnect the battery and test every function of the HVAC and everything else that you had disconnected for the install .

Hope this helps someone in the future when they install the Long HVAC conversion harness to facilitate mounting the HVAC module in its factory locating

Good stuff, thank you! That's my next mod, the RA4 with the HVAC change. Does the passenger side vent need to come out for the install or did you do that for the pictures?

Nice writeup. I have been considering mounting mine in the factory location when I have time. I also have a Getupkid harness and it works great but it would be nice to actually mouth the module where it is supposed to go.

Yes sir , you must remove the lower glove box ,passenger's side vent assy and the far right outer most side panel. To install the module in its factory location.
It would be nice to remove the upper glove box or cubby if you don't have the upper glove box.
I didn't remove mine , in hindsight I kid of wish I would've especially for the tye wrap install.

No tools required , I just removed the lower GB to gain access to the backside of the vent , then pinch the plastic push pins from behind and gently push outwards . At that point pull back about 18" of the door seal and remove the outer most R/S plastic close out panel in similar fashion as the vent .

This far right panel removal is a must because you need to install the screws to mount the module .

This photo is from post 5 or 6 in the conversion thread I posted the link to above .

Looks good Ronnie and great write up! There really wasn't a detailed one for the 7 speed folks (except for the PDF instruction sheet in post 2).
Glad everything went together well for you and a big thanks to Cptwing, Getupkid, Mondo, Indaram and others for putting the original info together!

2/9/17 Edit:
Just an FYI for those that need a harness, there will be legit vendor/way to get one posted in the next day or two.

Thanks Rick !
Yep it was an easy install , well worth it . You definitely should do it & I highly recommend getting an extended harness.

Thanks all, just got it in, everything works, except TVs A/C. I think I might have the wrong Temp Control Module. Are there different ones?

Here’s the one I got:
