Improved Access to Wiring Under Dash

I’d like to neaten up and rearrange some of the wiring under the dash to the left of the steering column without straining my ancient muscles and tendons.

i think it would help if I made more room by removing the trim under the steering column. Does anyone have advice on how to do that?

Thanks.

The trim covers the wiring to hold it in place so as not to interfere with normal foot movement while driving and parking. If you attempt to bundle the wires they will be less accessible for any tasks involving the wire connections.

Do you have a specific reason to rearrange the wiring? Bundling of wires helps to groom visible wire routes, but under the dash are not visible and if you need to work under the dash, your bundles will make work on connections more difficult and you will end up cutting the ties for access.

Thanks @njamesj. Rearrange might have been the wrong word. There are already a cluster of wires hanging down to the left of the parking brake pedal. They are visible in the previous photo.

i don’t know what they are but I’m thinking they may have to do with the dealer’s installation of the unwanted Lojack. I’d like to neaten it up, and maybe even remove the Lojack which draws a little power when the truck is off.

Separately I intend to install an OBD-2 splitter and connect a ScanGauge cable under the dash. I wouldn’t do any unnecessary bundling but would like to get my head under there to have a look.

Removing the trim might help.

I assume you financed your Ridgeline and whoever is holding the title is requiring the LoJack. If that is incorrect and you own the Ridgeline, then you could just take it right back to the dealer and have them remove it.

In any event, the lower dash trim pulls away pretty easily. You have to remove the left end cap first (which I think in another thread you have already done) and then just pull the lower dash straight toward the rear (toward the driver) and the clips will pop free. Having said that, I'm not sure pulling the lower dash free will help you much. It looks like the LoJack is back near the firewall near the main interior fuse box. There's a lot of room behind the left kick panel and you could just try tucking the wiring back behind the kick panel.

A couple tricks to make it a lot easier to get access to the fuse box area...
  • Remember to move the driver's seat rearward all the way. That should give you more room to work.
  • Then find a way to run a plank across the bottom of the door opening to lay down on. Imagine laying a wide board from outside the Ridgeline in through the door opening. Prop one end up on something roughly the height of the Ridgeline floor. The other end will lay on the Ridgeline floor. Laying down flat on the plank is A LOT easier than contorting yourself. You can even lay a blanket on the plank to make it more comfortable.
Honestly, I can't believe they left that wiring loose like that. That's a hazard. You can absolutely hook your left foot in that excess wiring. Independent of who has the title, maybe you should go back to the dealer anyway.

Edit to add:
Here's a picture where I pulled my lower dash away to gain access to the array of buttons in front of my left knee:

Notice that there are multiple wiring harnesses connected to the lower dash because of all the switches.

I didn’t finance it. The dealer installs Lojacks on all of their vehicles and then adds it on the supplemental window sticker along with nitrigen, some kind of door edge protection and any thing else they can think of to artificially increase the asking price.

i located the Lojack by contorting myself into a painful pretzel and poking my head under there. I can remove it myself. The Houston dealer where I bought it is farther away than I woukd drive just to have it removed. I have a nearby healer who will be servicing the RL (and my wife’s Pilot).

Your wide board idea seems inspired. That’s what I will try.

Remove it yourself, they are a joke anyway....there are handheld jammers for about $350 that professional car thieves use to circumvent them and also GPS, Northstar, 4G/5G etc using one small device... One examole

Interesting. I wasn’t aware of the jammers.

I’m not concerned about professional thieves as my area is packed with F-150s and other more desirable targets than my little red pickup.

But, I don’t see any advantage to keeping the tracker and will take your advice and remove it. Thanks.
