Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis

Also got the ECU engine harness completed and installed. I re-routed the wiring and came up with my own branch scheme. Got it all taped up then all wrapped up in Classic Braid from Painless Performance. That stuff looks really good. The only drawback is the kit I ordered (chassis pack) doesn't include nearly enough self vulcanizing tape (used to wrap the joints in the branches) but I guess they don't count on you wrapping an engine harness and a vehicle harness.

Here's the harness after re-routing, prior to getting wrapped. For the record, I officially hate the universal harness after going through this process. Where I have the ECU I have almost 4 ft of excess harness to contend with, yet I'm still super tight on one branch due to the lengths being already terminated. If I had this to do over again I'd get an unterminated harness, but I went ahead and got the harness with the ECU. Probably works for most people and makes their life easier, but for guys like me it drove me up the wall. Oh well. It's done. It's installed for now. It may get yanked in the future.

Little closer shot showing all the branches. For reference, I really only need about 1' of trunk vs the 5'+ shown above.

Here's that giant grommet again, this time on the harness. Nope I didn't cut the grommet and the connectors are all larger than the 1" center hole and it doesn't stretch enough to clear the connectors even after 10+ min in boiling water. So yep, I wound up removing all the wires from each of the ECU connectors. I of course have them all in a spreadsheet by pin, wire color and function so it didn't bother me, but I still only did one connector at a time.

Here's the harness all wrapped up. Way too long and I even have some wires in a loop they were so long. Live and learn.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis

This weekend after I got the engine harness installed I started on the vehicle integration. I'm running a Holley Dominator ECU, so it's got tons of inputs and outputs. It has a dedicated set (J2) for just that and then if you aren't running DBW or an e-Trans (like a 4l60e) then J3 and J4 become wide open for more inputs and outputs. J1 is now reserved for the engine. BTW, J1 and J2 have 2 connectors, so yes, that's 6 connectors on this beast of an ECU. And they all have at least 24 pins each. Fortunately I've only gotten in to around 20 extra pins as of right now. But add in wheel speed sensors for traction control and maybe some linear POTs on the suspension and there's a bunch more wires. This thing is setup for Turbos, NOS, water injection, flex fuels if you want, and more.

Just a bunch of extra long, ready to cut to length unterminated wires (they do have the ECU pin already crimped on), a couple blank connectors. That's more like how I like to roll.

Just a spreadsheet and my mind. Hmm, what color wire should I make this function?

Ok, a slight break from wiring. I needed to get my gauges to an installable point. Now, I had already designed this layout before, but I never made a proper panel until today. So here it is, all $16 of that 14 ga plate from Lowe's and some time. A bunch of time. Boy I wish I had a plasma cutter. But I don't. Shown here raw, which it will stay for the near term. I had planned to paint it, but this raw look with some of the sanding swirl from the DA still showing actually has me thinking it might stay raw. Well, a little clear would get shot on to help keep it from rusting since it's carbon steel.

All electric gauges mean lots more wires to deal with. I've got some connectors to install that will make this look a lot more manageable.

Very cool build and great attention to detail. I'm excited to hear it when you fire it.

Re: C10CJ: A Pro-touring '71 Stepside on a No Limit Pro-C10 Chassis

A couple of random questions for you...

- Are your wheels going to fit in a stock wheel well?
- What paint do you use on small parts, eg the steering column bracket? I haven't had very good luck with anything in a rattle can besides this VHT Epoxy stuff so far.

Thanks man! Wow - I didn't realize it'd been so long since I last logged in! Some vacation, busy at work and I haven't made much progress either.

Wheels:
Fronts - Yes, at least all the tests I've done so far support that. Until she's all together and sitting on the full weight and I run the steering lock to lock I reserver judgement.

Rears - No ... The stepside fender fits about a 10.5" wide tire (sidewall bulge to sidewall bulge with a little room) so I had to cut the bedsides to fit the tire I'm running (~12" wide) as I want the tire to be able to tuck. If I didn't want to tuck I could have gone with a different backspace but then the wheel would have stuck out more than I like.

Paint for the small stuff - I've been using the same exact stuff you linked, VHT epoxy satin black. I like the color and it seems to hold up pretty well if you follow the prep and application guidelines. So I'd say we have had the same experience. And for the rest wondering, this stuff is actually expensive. The can only covers ~14 sq ft if you're lucky. I've gone through a lot of cans.

Where did you get the large grommet if you donít mind me asking?

Hey beaterku, no worries on asking, I'm happy to help. Turns out, that giant grommet was in the Holley LS EFI package I'm using. I hadn't paid any attention and was digging through the pile of crap on my bench and came across it and was like "hmm, I ought to try this thing since I have it" and at the time I had no clue where I had got it from. I did a quick scan on the Holley website and didn't see anything similar sold separately, but you might be able to give them a ring and see if they can tell you where they get it, reference P/N 550-612. I was looking at various options from seals-it if I hadn't come across this one (since I had no clue I had it) or it didn't work out.

Good to know I'm on the right track... they have a 6-pack of VHT with significantly lower cost per can, but yeah it gets pricey. Well worth it in my opinion though, since it doesn't require primer!

Yep! That's what I like most is no primer. Just clean up the surface and spray away!

VHT Epoxy Satin Black has the same sheen as the 'old school' Krylon Satin black (before they changed the formula). Beware though.... It does not like it if you don't follow directions (specifically the re-coat time line). That's the only thing I dislike about it.
