What did you guys do with your Big C Connectors on the passenger side there ? Trace back and eliminate ? Tuck and hide ?

I am going to tuck and hide mine. I don't think there is anything in that part of the harness that is important after switching to the Holley.

Has anyone came up with a way to run factory gauges with these Holley setups? I'd imagine it's probably like the guys running the MS3 systems and I believe they are splicing into the factory ecu??


What's the benefit of running these Holley's over the factory ecu? I'm going to get my Nitrous setup someday when funds replenish and I know that running an aftermarket setup would be beneficial. Do you guys gain a lot in tuning? Or increased reliability Driving?

Assignable input and outputs, built in wideband, Logging. I think for a daily driver with little mods you'd be better off with a stock ECU, Heavily modded or strip only the Holley system allows you to control/monitor everything and log runs. I'm running a Dominator ECU on a supercharged 2000 S10 that's daily driven.
I also have the Holley dash so one screen displays Speed/RPM/Oil pressure /Coolant Temp/Oil Temp/Trans Temp/Volts/Boost/AIT's/AFR/Flex fuel and it can monitor anything I want/need it to, It can also be configured as a virtual switch panel.
Basically if you want to control/monitor something the Holley will do it.
You can configure multiple fail safes so you run to hot/no oil pressure/over boost and so on it can be configured to pull timing/shut down whatever you want it to do.

It's not possible. Sucks but if you are at the level of needing standalone efi forget about it. Holley sells a GPS device for an odometer in the digital dash. Holley is hands down the best efi right now. You gain so much switching to it. The new V4 is endless you can do anything. You will see things in your log that the dash doesn't show such as the flawed oil pan design losing oil pressure on launch to dual vss traction control

I use a 97 dash in my 01. Just use the correct sensors.

I would not want to use 20 year old gauges in a car I was running holley efi. We run the digital touch in everything we can or after market gauges. The stock clusters are not that accurate in the first place.

I am installing HP EFI at the moment. All of the connectors on the passenger side can be unplugged. I am currently tracing all the wires back to the fuse panel and deleting what I don't need. Just wanted to confirm what you had said.
