### ⭐⭐⭐⭐⭐ 







  
  
    nice kit
  

*by W***S on Reviewed in the United States on 12 September 2023*

I used this to wire in a secondary fuel pump for a turbo LS RUNNING A WALBARO 450. This kit bas nice connectors and a good heavy wire. I will be using them for future builds.

### ⭐⭐⭐⭐ 







  
  
    Easy setup Quality Okay
  

*by M***Y on Reviewed in Canada on 18 May 2023*

So Far so good.  We'll see how things progress quality seems good with tin plated contacts and wire.  The relay needs a little muscle to get it in the socket.  I modified quite a bit of the unit to make it fit my application but that's my thing.

### ⭐⭐⭐⭐ 







  
  
    Nice complete kit, CCA wire
  

*by R***R on Reviewed in the United States on 9 July 2023*

Complete kit with a proper 40 amp large leg relay, should help with overall function and longevity.Came with everything needed to install.Only downside so far, the large gauge wire is coated aluminum.But for the price, kit is hard to beat.
