What should I use to protect the ECU plug

I have a question about the ECU plugs on the Power commander. The factory ECU plug has a clear vinyl boot that protects it. When you install the PCV, you end up with multiple plugs where there used to only be one. I am assuming that all of these plugs should have this same "boot" to keep water out, but the power commander did not come with any. I checked partzilla, but they don't offer the boot seperately, it comes already installed on the various wire looms. I tried a few auto parts stores and they didn't have anything either. Just curious what other people are using. I thought about picking up some clear hose from ace hardware, but not sure this could withstand the high heat, sitting right next to the head cover. Suggestions???

BTW, happy to photograph it if my description isn't clear.

Thanks!

 

I know what you are talking about, the problem is that those boots are put on before the connector is attached as the small end won't fit over the connector. I don't know how much those boots really help keeping water out since the small end isn't a tight fit around the wire and water can just run down the wire and into the plug. I was thinking you could use heat shrink if you can find it big enough to fit around plug. Heat shrink that big won't shrink down enough to make a tight fit around the wire but will resemble what honda uses. It will eventually shrink down around the connectors from engine heat so you would need to cut it off if you wanted to disconnect the connectors. Look for the heatshrink at a commercial electrical supply store. You could also fill the connector with dielectric grease.

 

Fill the back side of the connector with silicone and seal it good, then fill the connector with dielectric grease and your done. No more water worries.

 

Thanks MrSleep,
I thought about the heat shrink, but I am looking for a solution that can be easily moved to the side and then repositioned in case I ever needed to bypass the PCV for troubleshooting purposes on the road. If I can find a suitable material that can withstand the heat, I figured I'd just zip tie the ends to create a semi water tight fit. As you pointed out, the factory boot is far from water tight, I think its main purpose is to protect from high pressure water, like at a car wash.

 

Thanks Zen, thats a thought. I am not a huge fan of the dielectric grease, i hate that it seems to always get other places and attract dirt.

 

What your supposed to do is only fill the connectors air-gap. This is fairly small and many use way to much grease. Apply a small bead down the middle and push the connectors together. Then separate and look for dry spots. Add a little more grease and try again. Once you have a full connector add a small blot to the center of the connector and put it back together. Wipe off any excess and then use a degreaser like a lemon water spray ( I actually use warm water and lemon to clean off dielectric grease. Sprayers can be found in dollar stores). Make sure its clean and all you will have is the road dirt that sticks no matter what you do.
I know some guys in the hotrod world use a spray wax on connectors to keep them clean and make cleaning easier, I havent done it to mine but was thinking of it.

 

Thanks Zen, might try this!

 

Ha ha, I do have a tendency to over think things. Thanks for the input, its probably spot on!
