Questions

Before you order.

What ships free, what comes off the price on its own, and how a harness order starts.

Standard shipping is free on orders over $400 in the continental US. Under that it is $10.95 up to 1 lb, $19.95 from 1 to 5 lb, and $34.95 over 5 lb.

Outside the continental US, including Alaska, Hawaii and the US territories, email admin@faustec.com and we will quote the shipping. Carriage to those addresses varies too much to put a flat rate on, so checkout does not offer one.

Buy a Haltech Nexus R3 VCU and the backshell goes in your cart at $0.00 on its own. Nothing to add, no code to enter.

The offer is the Nexus R3 only. It does not run on the R5 or the S3.

Yes, and there are two ways to get there. Buy the CARTEK PDM-5 Radlock Kit as one listing, or add the Radlock and Pin to a PDM-5 and $15 comes off automatically. Both land on the same price.

The PDM-8C Radlock Kit is a single listing, already priced as a kit.

Tell us the combination and we'll quote it. Turbo setups, relocated components and swapped sensors are all normal here.

No. Every harness is new construction. A modified core carries the age and the damage of the harness it came from.

Still unsure which harness your build needs? Send us your combination and we'll tell you.

One harness. Built to your combination.

4L60E, 4L70E, 4L80E, T56. Drive-by-cable or drive-by-wire. Whatever you have changed on the engine. Pick the combination, we build the harness from scratch around it.
