Tach signal adapter
As with most swaps that I have been involved with, the tach signal from the computer is corrupt and the signal is lost, with the plug and play set up that I ordered is the greatest thing (NO CUTTING AND SPICING) just unplug the coil pack for each bank and plug in the adapter harness and mounted the adapter on the firewall and run the tach wire to the tach,little square box on upper pass side firewall look close to see

Super simple
Exactly how it is advertised. Comes with everything. Plug and play all I had to do is solder one wire for my power safe nitrous gauge so it could read rpm for the widow switch feature.
Also customer support was 10/10 straight to the point and knew exactly what I needed to get my system working and if anything else I had would interfere with it.

#9123 didn't work for me
I purchase a #9123 harness and adaptor to power my #2300 tech on a LS3 swap.
It didn't help and I weasted a lot of money on it. It looked very impressive.
A very easy harness to install.

LS Tach Signal Adapter
I reviewed the data involving clean LS1 ecm tach signals. The resistor fixes are a carnival of tricks that will burn more of your nerves than pulling that $170 from your wallet.

Hello. I have a client with a 69 Firebird that has a GMPP LS3 crate engine with an OER hood tach. The LS3 tach signal is 1/2 actual RPM. Would this device correct that?
This product is not designed to drive an OEM tach. It will only work correctly with our tachometers.

i have a 2003 5.3 ls engine in a2002 jeep wrangler that had 4.0 liter 6 cylinder.will this operate the factory tach and if so do you know what wire i should hook it to?
We do not have definitive data on this working with factory tachs. This is built to work on Autometer tachometers.

I have a 2010 camaro 6.2 v8. I have a factory tach which works fine but I would also like to install your 5"auto meter shift light tach. Will AUTO METER 9123 adaptor work on my car?
The 9123 plug and play adapter an harness will work on your car.

Hi, I have a 68 Camaro with the tic tic tach and a LS3 crate motor and was wondering if this would work with the combo I have.
The 9123 should be plug and play for your application.

i have the American Muscle 5" tach. Do I need the 9123 with a 2005 LS2 out of a 2005 Corvette. Original harness.
If you could, send our tech team an email at service@autometer.com.

Do all LS engines need the 9123 signal adapter to use your tach ?? I have an Ls2 from a 2005 corvette.
Typically our 9117/9123 would be needed for such distributor less ignitions like an LS Motor to produce a tach signal for our tachometers. If you take a look at 5284, it would have an instructions manual for LS Motors with more information on incorporating a 10k Watt Resistor, and if necessary, the 9117.
