I bought a 4D Tech start/stop eliminator for my 25' Explorer ST and it failed within 2-weeks and I returned it - they are made in China I believe... Easy to install, yes.
Fortunately another company (shown below and made in the USA) I wanted to buy my start stop eliminator from and that I've purchased and used in the past, came out with their's for the 25' Explorer and I purchased it after the failure of the 4D Tech. It installs in a completely different area than the 4D Tech does but it is similarly easy to install. It takes litterally 2-3 minutes to install it.
