At the risk of cluttering the thread – I’ll give history on the taillights (eventually I’ll chronicle the progress of the entire car in another thread) *Mod(s) sorry if this is wrong area for this… please move to appropriate area if necessary.
As you probably know, the first gen G35 sedan tails look like this: (real old pic)
One of the things I never liked about the sedan is the aesthetic design of the rear turn signal (I call them “cat ears”)… So I decided to make them look the way I think they should.
The challenge was to make the tail/brake lights flash as a turn signal (like the first gen FX) so I could omit the cat ear all together by painting over it. Well, this was a real struggle! No one had ever done it and no one had any suggestions when I posted the concept on other forums. I thought it would be a relatively simple wiring change (and even after the fact many ppl still think that) – couldn’t be more wrong!
Cars these days are way harder to trick and make do what you want them to. The BCM is so temperamental and finicky (obviously controls many things, including the turn signals and taillights). The only way to do this by re-wiring would be a bunch of trial and error and BCM combat by using a series of resistors and relays… I didn’t have the time or desires to deal with that – and I wanted a clean way to get it done.
I contacted Kevin Pierson at KPTechnologies to make a module to wire in line (between taillight and BCM) – for the most part Kevin produced what I needed. A small module that tucks in the rear panel (next to the taillight) was wired in. But then the BCM battle began… lots of trial and error still took place. There was voltage fluctuation and in some cases feedback that caused all kinds of gremlins (I won’t bore you with the details)… we tried additional resistors (in some cases helped) and ultimately added one more relay… after a bunch of patience “try this, rule out that” – the end result was this:click to see blinker in action: [IMG][/IMG]Now the seemingly easy task of getting the OEM blinker not to blink... Granted, it would be painted over to match body – but I didn’t want residual light shinning/blinking through… simple enough, wire in a resistor. WRONG again! Tried several different configurations and got a good lesson in Ohm’s law from studying and trying to calculate what should work… well that ended up being as useful as the two years of Spanish I took – I never used what I learned (we couldn’t get any resistors to work entirely)… First thought for most people is “remove the bulb” - problem is the BCM thinks it’s burned out and you get a hyper flash. Result = tin foiled wrapped around bulbs (sometimes the simplest ideas actually end up being the best result.
So for quite a while the car looked like this:
Kida cool and definitely different (that’s the theme of my car, subtly different; one of the reasons it’s named “Grey Ghost”).
