Sanchez Posted April 5, 2012 Share Posted April 5, 2012 So I have just a few wiring problems with my 240z I could use some help with: 1. I need a new ground wire for my ignition, my current ground wire is frayed beyond belief (just upgraded to the Pertronix ignition). 2. I just put in a new 60-amp alternator and heard that it will destroy the stock wiring pretty quickly, is this true or should I worry about it? 3. I am planning on upgrading many of the lighting to LED's, could somebody who has done this leave a quick synopsis of what you did (part numbers, if new wiring was needed, if you needed resistors, etc...) Lastly, I started on step three by purchasing the LED Dome Light Upgrade from MSA. Though I bought the upgrade specifically for the 1970-1973 240z, 1973 is the car I have, the pieces I received were too large for the dome light. When I asked MSA if they had sent me the wrong part they said, "No, it just takes some moving around to fit." Well I tried every possible placement and either the upgrade would fit and I wouldn't be able to press the light on or the LED's would not fit. Has any one else attempted this upgrade and, if so, how did you do it? The dimensions are a 35x35mm square with a festoon attachment, it is a 4x4 grid of LED nodes. I am now even more confused because in my research I stumbled upon a post by Mezzz, on classiczcars, who claims he got the same upgrade from MSA but his fit perfectly and looked like this: Quote Link to comment Share on other sites More sharing options...
ZT-R Posted April 5, 2012 Share Posted April 5, 2012 I bought the same thing, i just have it dangling at the moment I will try to install the thing shortly. Quote Link to comment Share on other sites More sharing options...
NewZed Posted April 5, 2012 Share Posted April 5, 2012 2. Don't listen to the person who told you this any more. Quote Link to comment Share on other sites More sharing options...
Sanchez Posted April 5, 2012 Author Share Posted April 5, 2012 NewZed: Thanks for the info, I had heard it somewhere but I just wanted to be sure. I guess I have nothing to worry about. ZT-R: When you finish your install, if you are able to, please leave a fairly detailed description on how you made everything fit correctly. I have been monkeying around with the thing recently and still have not had any success. If I cannot get it to work properly in a few days I will probably return the part and get a new LED festoon bulb from superbrightleds.com instead.

Sanchez Posted April 22, 2012 Author Share Posted April 22, 2012 Found the solution to the dome light from MSA, it is not as simple as they claim the install is. Steps: 1. Remove the dome light entirely from its location (disconnect the wires and remove the entire console) 2. Completely disassemble into the three basic pieces, a black box, a lens cover and the metal siding for the lens 3. Take out the old festoon style bulb from the metal prongs 4. take a pair of metal cutters, angled works best, and clip the unnecessary metal off of the prongs (the metal overhanging from where the bulb sits) *Be careful, the prongs are held on by small rivets, I broke one on accident and it was a pain to replace* 5. Reassemble the entire console and insert the new LED bulb and attachment, it should sit loosely but will be able to be pushed in fully *There is a plus and minus side to the bulb and the prongs, though not at all marked, if it does not turn on at first flip the points on the festoon node* I will try to upload some pictures.
