LSX Specialties is located in the Pacific Timezone. West coast time. (Medford, Oregon)I’m usually opening the shop up around 8:30am. That’s when I get the shop phone and start replying to calls, emails, text messages, Facebook messages, instagram messages.

If you call my shop phone 18 times between 9:00- 9:30 AM from Florida, that means it’s 6:00-6:30 AM here. I will not get your 18 missed calls for about 2 more hours. I’m not avoiding your calls, I’m just not in the shop yet.

I appreciate the calls! Keep them coming. Thank you all!!

This little jumper harness was built to connect both upstream O2 sensors to a single sensor on a turbo downpipe on a 1999-2007 Silverado, using all the factory wiring.

This was a very custom harness that was ordered. The customer measured every sensor using a piece of wire to the ECU following the path he wanted his wires routed. Gave me all the measurements and all the measurements on loom lengths. This was a great way to get an exact fit.

Start to finish process of rebuilding a core sent to me.

This isn’t the typical retape and add a fuse block that most rebuilds are. This is fully stripped, inspected, extras removed, reloomed in seamless nylon, reassembled.

All wires can be replaced/repaired as needed and all the things that need changed to fit your project can happen much cleaner and easier. You will see the damaged wire and butt connectors that were hidden and able to be repaired in the process.

This one specifically got EV1 injector plugs, 4L80E swap, DBW to DBC throttle swap, speed density for boost and the ECU relocated to under the dash.

This is the same process every harness that’s sent to me for rebuild goes through.
