Well after a few minor dramas over the last week, being 2 out of 4 oxygen sensors failed so i have now replaced all 4 (FYI if anyone needs any parts for Jeeps, goto
rockauto.com they have everything ridiculously cheap and very fast freight, 2-3 days from the US), also changed the alternator charging style from a computer control voltage to an external adjustable voltage regulator. For $100 including postage this is the best little kit i have seen. For those of you that have never heard of these, then try googling Jeep external regulator, there is a guy in the US putting these kits together for the Jeeps, best kit going.
Quick Start Alternators
Also on ebay for less postage cost
Also in the process of all this i finally managed to finish trimming the back out and also putting the fridge in.
