2004 ls swap with 99 z28 cluster - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Bagwurxc10 · 07-20-2014, 04:36 PM

I've been doing research on z28 cluster for my ls swap. My donor 04 Silverado cluster has a white engine speed wire and the 99 z28 cluster doesnt. I'm assuming that the tach signal comes from the serial data, I just wanted to confirm or someone point me in the right direction. I've seen the same combination used.

Bagwurxc10 · 07-20-2014, 04:59 PM

Here's what I got...99 z28 cluster

Bagwurxc10 · 07-20-2014, 05:02 PM

2004 4.8 drive by wire and 4l60e. I sent pcm to Brendan at lt1swap.com

Bagwurxc10 · 07-20-2014, 05:04 PM

Fabbed my own brackets for motor mounts

Bagwurxc10 · 07-20-2014, 05:06 PM

Just waiting for ups to deliver my fuel system and pcm. Hopefully I'll have it in this coming weekend or the following weekend.

Bagwurxc10 · 07-20-2014, 05:09 PM

A quick pic of the patient. ....lol

Bagwurxc10 · 07-20-2014, 05:19 PM

10" re audio in a down fire box housing the shifter and cup holders

Bagwurxc10 · 07-20-2014, 05:23 PM

My kick panels

Andy4639 · 07-20-2014, 05:28 PM

My harness had the tach off the ECU direct. So yes it should. You may want to call the LS1 guys and make sure though.
Interested in the camaro cluster and how you plan to incorperate it into the dash if you have any pictures.
Nice looking ride by the way!

Lee H · 07-20-2014, 05:31 PM

Great looking project.

I'm shooting for this. I'm using another members idea.

His gauge pics are on page 1 about half way down. He did an awesome job.

Andy4639 · 07-20-2014, 06:24 PM

Yes he did. Very nice. I like that look. I wonder how he mated it to the metal dash. Did he are you weld some bolts to the back side of the metal dash are what?
I have been thinking about redoing mine and counter sinking the gauges to slant up some to see them better while driving.

It's anchored to the original gauge housing with L-brackets and has a lexan face.

Bagwurxc10 · 07-20-2014, 06:32 PM

The members name is imsuchaman55 has been helping me with my wiring questions. He is the member I borrowed this gauge idea from.

jborders · 07-20-2014, 06:44 PM

I've done the same with a 97 z28 cluster.

jborders · 07-20-2014, 06:45 PM

Here's the tach info if you still need it.

Bagwurxc10 · 07-20-2014, 07:33 PM

93-97 z28 clusters use a tach wire and the 98-02 clusters use the serial data wire to drive the tach...at least that's what another member told me.

jborders · 07-20-2014, 07:38 PM

Sounds right . Brendan's site has all the pinout info .

Bagwurxc10 · 07-20-2014, 08:07 PM

Yeah...I wish someone had all the answers for this ls swap. Brendan has done a lot of good articles on this stuff but he has never used a Silverado or a z28 cluster for a swap. We've been emailing each other on this subject. I'm doing this thread for this reason. Everyone shows the finished product, but never documented the wires used or how they got what to work. I'll do my best to keep this thread going as I figure it out. I came across the resistor idea that you posted on a ls1 site I believe. If I could get all the answers on one thread that'd be great for someone else in the future. Thanks for the reply on what solved your problem.

jborders · 07-20-2014, 09:00 PM

You're right it does from the the class 2 serial but not directly form the PCM . I would try it from the PCM though it might work . Pin 58 or 59 are the ones I'd try on the blue connector.

Bagwurxc10 · 07-22-2014, 10:39 AM

Fuel system for the swap

Low Elco · 07-22-2014, 01:00 PM

Verrrry interesting.... I wanna see what you come up with!

SierraMtns · 07-22-2014, 01:52 PM

Why did you pick a 4.8 over some of the other LS motors?

Nice looking stepper. Cool idea with the cluster.

69sinker · 07-22-2014, 10:19 PM

I used an 02 Camaro cluster. Works great, I've got a lot of notes and pinouts if you need any info. Dave
