Glad to announce a Huge update!
Took a huge risk and Ordered a numbers matching FEM on ebay. Plugged it in (no programing needed) and it work perfectly!
Also happy to announce that the oil light is also now gone. Therefore not an oil pressure related problem.
To conclude, The symptoms of the full headlight assemblys, fog lights, instrument cluster lights, oil light on cluster and peddle level switch not working have all been fixed by replacing the FEM.
Thanks Joegr for all the info and help. You are the man! Really can't thank you enough.
