i just got my MS hooked up to my 96 5spd 420a venge and had a couple little problems


1. My stock tach no longer works but the MS unit has a tach output function.....could i simply just splice the stock wire into the MS output or do i need an after market tach

2. The shop that is workin on it said my alt. is not charging the battery back up he thinks its not getting a signal....would this have anything to do with the MS unit or did maybe a wire just get cut in the MS hooking up stage

3. my coolant temp gauge is also not working can this be remedied as well....

hopefully you guys can answer these questions for me so i can enjoy my newly boosted venge soon
