Very Nice product. Fits perfectly in my 1981 chevy c10, and customer service and tech support were top notch.

I have two of these and they are working perfectly on my El Camino and my Catalina convertible. No complaints.

Worked just as it's supposed to in my 94 LS swapped Crown Vic

Easy install with instructions made very clear

Well packaged, instructions were easy to follow and it worked first try.

Easy to install instructions are awesome easy to read follow instructions it made my LS swap step by step easy if it wasn't for PSI harness I probably would have to hire somebody to do it I'll definitely be back on my next one thank you PSI for a great product and customer care after the sale.

The, TCC breaks switch is awesome product most definitely the solution to my LS swap in my custom classic Camaro, I recently added Terminator X Max the instruction from Holley was not very clear, As noted the drive by wire and the torque converter lock up, after tons of research. I purchased TCC/ Brake switch from PSI. The instructions were clear plus video I Connect the wires accordingly, Holley unit started working with no issues along with the brake lights and the torque converter lockup, green light indicator.... Thank you! PSI .... Two thumbs up!

FYI Holley Terminator Max the drive by wire red/white wire that causes limp mode issue to the throttle body. Please note the Terminator X Max is a great product however instructions that come with it was confusing, after tons of research if you go to the Holley help me wed page! on system it shows no need to connect the red and white wire brake switch, Yes, it is a safety mode keeps Holley from being sued, just in case the throttle sticks wide open. I did not connect red/white wire to the Tcc brake switch, Yes, the limp mode went away. I understand the discrepancy and safety that needs to be applied between the two instructions. Yes, drive by wire is electrical component, however it was very costly at my expense.

walked me thru the entire purchase process

A quality part and easy to install with clear instructions. 

Excellent company for an LS swap. They are very helpful and priced fairly

Was easy to install and wire up.  So far a good overall product.

I love how you all have thought of everything to complete our swaps. This part is good quality and has lasted 4 years since I’ve done my swap, and it still works as advertised. 

This brake switch arrived on time and worked as expected. The directions provided were clear and easy to follow. Also, the installation video provided by PSI further confirmed that my installation was correct. Thanks to their high quality products and excellent sales and tech support, PSI has made my LS swap easier than I could have imagined. Thanks PSI!

Product is exactly as described. Quality product with easy to use instructions. Highly recommend.

Made change for torque locking and unlocking easier and no guessing. Wiring harness is great as well. 

We are restoring this vehicle with upgrades. The ordering process was simple as well as application. 

Worked great. Fast shipping. Definitely buy from you again.

What can I say, PSI is great, customer service is unmatched

Exactly what I was looking for. Works great and a great price. The shipping was super fast. Couldnt be happier, will definitely buy again on my next swap.??

worked right the first time easy to follow instructions great product

I bought my LS Harness back in 2013. I wired the car and never had the chance to fire it before tearing it down for paint. I am finally assembling the car and fired it for the first time. I have to say I had no issues even 6 years after purchase. Thank you for a solid product!
