My car is a 280zx 1981 so it always have a internally regulator I think... that's what people told me..! The blue wire in the t goes to the volt light and that's work! But if I disconnect blue wire it stops running whit key turn off... I have a wiring diagram from Haynes but I can't figure it it why it won't work...!

My old alternator went bad and I bought a new one... the old one was a Bosch from a Volkswagen and the guy installing it have cut my T-connection... The new one came whit a new T and I rewire it... now I can't turn of my engine... Key is of but engine still running.. and some how it power the ign... The voltage light works and the it comes of when engine runs... if I disconnect the blue wire from Alternator it works but it gives 15 volts to battery!! I'm going for a tuning shop in Monday to tune my MS so I'm desperate to get this work!!! I have now idea what to do! Pleas help

Does anyone have Kurk Mackay tune for MS? I have made som wrong in my tune and can't make it work! So I need a new tune to start over whit...!

I have done all my wiring and I think it is all okay! But how do I know if my ECU power up? I can't conect my tunerstudio to the MS ECU..? The 3 led's on my ECU are the going light up when ECU are powered? Anyone know??

Okey! Thanks anyway! Do you know if e need the stock relays? Or can I only use the MS relays to support fuel pump? The ignition I think I have found! And the TPS I can't find in the MS 3 harness..? Do you run harness frome Mackay?

I cant find this plug! I don't find a plug where fuel pump and ign are separated... I've got 4 wires from plug to ign. lock...! Black/white- ign Yellow - start Blue - Acc White - +12v constant Nothing I can use there... The relay box under hood? Can I connect MS there?

Thank u so much!!! Great info!!!

I have read the manual! But I don't know how Kurk maid the harness... so I hope that someone else have a mackay harness and know how it works! So where in my car can I conect to Ign so my MS relay switch on my MS unit? And we're can I conect my fuel pump? I understand how I conect the relay tho my MS but how do I conect it to the fuel pump in my car? These questions I can't find I MS manual??!!
