Avoid them at all cost. Those kits are made by a company called Nokya. Made the mistake to buy one kit. My history with the kit.
1)The relay they use are 30-85-86-87, BUT they are made in china and with quite unique shape and the 87s are splice to a single pin. After a few months of being used one the relay broke on me, since there are not replacement relays in that shape (at least in Argentina). I bought two relay made by Flosser plus twi relay bases and i rearranged to fit normal relays, on a side note Flosser relays comes with two 87. So no more spliced wire.
2)They don´t come with a Fuse, so i had to rewire the wires that went to the battery..... Not very safe to run a kit without fuses...

3)The wire is listed as 14 awg, but they are far from being 14 awg, they are close to 16 awg. So i changed the wires to 11 awg. Worst the wires didn´t even have solder on the conections...
4)The female sockets are not ceramic, they did melt.... Had to change the sockets to ceramics.
In the end i had. New Relays, New Wires, New Sockets... The only thing that still remains from the Nokya kits are the rubber wire covers....
Just my expierence with them. I was a bit lazy so instead of making the kit myself with quality parts i took the cheap way...
You get what you pay for.... and for 38 you ain´t getting quality.
