Yes, I would re-gasket the engine. I also sent the heads out on my LS1 with 98K miles & had a valve job done.

If you have a harness & an ecm, I wouldn't pay that $1500. You can relocate the ecm under the dash when you reconfigure the harness. Is this a cable throttle body or DBW? I'm not sure when the change occurred.

dbw, I texted guy I bought it from to see if I can get the pedal out of it

What number is on the ECM and what does it look like?

I believe it should be an E38

One of these will work just need to know if 58 or 24 and what injector. Or I looked at CBM motorsports who will make a new harness any length you need even put ecm in the trunk.

Not sure how to tell, but at some sites I was looking I thought it said E40. I think it's 24, it looks black

Take a picture or your PCM please. And include the hardware and service numbers, if possible.

Here you sir

 

[modern malibu]

howell engine developements offer a lot of wiring addons along with reflashed ecms and terrific support . sudgest looking at ls1 tech website Lots of help there and links to vendors under the conversions and hybrids section.

 

[rpol78]

Looks like an E38 with a 58x reluctor (i.e. 2006 Corvette LS2).

 

[Mikes1970]

OK I was looking at the crank sensor, so sorry. Back by the starter there is a grey plug to the block. So 58x

 

[Alwhite00]

OK. It looks like the $200 harness may not work for you but lots of options out there.

also google "2006 corvette engine wiring diagram"

Just talked to Howell, they have everything I need. I feel much better after talking to Phil. Thanks Modern Malibu

Just out of curiosity have you looked at Speartech? I've always heard good things about them and am planning on using them for the LS based supercharged 396 for my '67.

 

[Mikes1970]

Yes I just looked there and they sell the Howell. I don't think they are a manufacturer

My understanding is Speartech builds their own harness and does their own ecm programming. I've exchanged emails with them a couple times on building an E67 based setup for my build. They specialize more in stock or near stock configurations than the high performance market.

FWIW - I have no affilliation with them.

From their website
"We have been building standalone wiring harnesses for the Gen 4 (58x) LS platform of engines since their inception.

We developed the first LS standalone wiring harness around 1996/1997 and have been building them in-house for thousands of automotive enthusiasts and professional companies around the world since then.

We build our LS swap harnesses on one of the many different live engine and transmission setups we have in-house which closely reflects the swap you are performing in your project at home or in the shop!

It is because of this process, our harnesses are the best running, looking, and fitting available.

The other major benefit of having us build your LS swap harness on one of our live engine and transmission setups is that we actually test run each and every harness we build prior to shipping. While your harness is running the engine, we have OEM GM diagnostic hardware and software hooked up to verify our work, and to help ensure trouble free operation once you receive the harness.

Once the LS swap harness has passed all of our diagnostic run tests, we cover it with our exclusive, heat resistant, woven fabric covering. This isn't a cheap see through plastic mesh covering, this is a nice quality covering and offers the correct fitting finish to your new Speartech harness that our customers expect.

The process and practices we choose to use takes a little more time, but we feel are necessary steps in order to ensure the end user has a good experience and gets something that "just works", and with proper installation, we know it will - we have already tested it on a live engine and transmission!

Put 23 years of GM Engineering experience - and now over 20 years spent perfecting the LS swap harness manufacturing process - to work for you!"

That sounds good, I must have maybe been on the wrong site. There was a whole lot of advertising for other companies. I will go back and look.
Thank you
