AAW Classic Update or Highway 22?

[Rhino]

I'm currently trying to decide what harness to use on my '68 Camaro build. I'll be integrating in bits and pieces of the harness from the 2002 TA donor that I used. In addition to the PCM and harness, I'll be using the steering column (with ignition switch, wiper and turn signals) and BCM (for control of power windows, locks, interior lighting, and the basis of a few theft deterrents).
Couple that with a custom gauge cluster, basic aftermarket stereo, Vintage Air setup, and aftermarket headlights/taillights and it seems I'll be using more non-traditional components than portions of the traditional OEM harness.

That makes me lean toward the highway 22 harness. On the other hand, I'm sure the install will be a little more involved since it's not chassis specific and I'm not aware of a source for all the lighting sockets and connectors that I'll need to interface with the stock '68 components. It doesn't matter to me whether or not I use the stock fuse box bulkhead. I don't intend on overly smoothing the firewall, but I'm also not opposed to moving it if the opportunity arose.



Knowing my setup, what would you choose? I'm trying to make a decision in time to take advantage of AAW's 12% off sale ending tuesday. Any help with that would be appreciated.

Thanks in advance!

Where do you plan on putting the fuse box? From what I understand the Classic Update is designed to fit in the stock location where the Highway 22 can be put where ever you want, like in the glove box for example. If you plan on relocating....get the Highway 22 for sure.

I don't mind relocating at all. That's what started my look into non direct-fit applications.

I started looking through the installation instructions for the H22 and I think it does meet most of my needs. Unfortunately neither of the options will fit my needs exactly. As an example; It appears there's only provisions for one fan. I'll be using the dual PCM controlled F-body fans which would require two relays. To remedy that, I've been planning on picking up an under hood fuse box out of a late model vehicle, but unfortunately it'll be duplicating much of what the H22 provides (Power for PCM, Ignition, Fan, fuel pump,etc..) One nice thing is that the H22 is quite a bit cheaper than a direct fit harness. I think I'm leaning towards picking it up and repurposing some of it's functions.

Has anybody had any experience with the builder series from AAW? It seems like it's purely a fuse panel and leaves the rest of the wiring up to me.

Here's something that Frank just came out with to solve the issue of more relays. https://www.pro-touring.com/showthre...i-Relay-Panels I'll be getting one of these along with the H22 when I get closer to doing my wiring.

Kinda steep for just a prettier solution to a $30-$50 problem.
I built my own relay panel with 5 relays in addition to my Highway 22 kit for next to nothing.

$85 gets you this bad boy with 5 fused relays in a weatherproof box.

Or you can buy your own Bussman box and make your own setup.

I was leaning towards the Hwy 22 but since my car is in driveable condtion I just went with the full update kit. For me it seamed easier since Im not starting with just a shell..I ordered it from Matt's Classic Bowtie and saved more then the direct discount from AAW.

I also got my new Classic Dash kit..This will be a nice X-mas..

Good luck on your decision!

In a strange twist, I ended up determining to use the full harness from my 4th gen F-body donor. I'll need to do a little rework to it, but for all the features I wanted to retain, and custom work I'd have to do to the H22 I felt it would be easier (and cheaper) to start with this harness.

When trying to make my decision I did call AAW for details. The H22 does have a few features the H15 doesn't, such as retained accessory power. For my purpose, If I did end up with an AAW harness it would have been the H15.

What does retained accessory power mean?

[Rhino]

Retained Accessory Power is the name of the feature in most modern cars where your accessories will stay on a set amount of time after you flip the key off. For example, you arrive at your destination, turn off the power, and your radio still plays until you open the door.

[gearbanger]

Okay, cool. So the hwy 22 has that? which circuits have that function?

Hmmmm. I have a Highway 22 system and mine doesn't have that feature.

I do not believe the hw22 kit has retained accessory power. AAW sells a separate relay pack for that.
