Rated 5 out of 5 by Autobahn444 from 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

Rated 5 out of 5 by NickM3131 from 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.

Rated 1 out of 5 by tire guy from #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.

Rated 5 out of 5 by dcburd from 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.
