today i was cleaning the wiring harness getting it ready to re-install into the engine bay and just happened to take the boot off covering the connector that leads to the sending unit and found this extra wire inside the boot. Im not sure where this is suppose to connect to. The wiring diagram in the fsm shows only 1 wire however this lead has two, and the harness only has the bullet connector (female end) to plug into. Any suggestions would be appreciated as usual..... 1973Z Thanks!!

I was looking for some small smt stuff, and foundthis. It's a replacement for an incandescent bulb? Maybe it could go in your gauges? http://www.chml.com/pdf/temp/1511A25W3.pdf thx

Step lamp?

While working on my body/dash harnesses, door switches etc. I came across this part of (for lack of better terminology) the "courtesy circuit." Found it in my FSM as two "Step lamps" that (I think) light up the floor, in addition to the dome lamp, when doors are ajar... the wires are Black and Red/Blue tracer, taped up on the driver's side of the dash harness and at the front of the body harness... I haven't seen a 240Z with these installed...were they for later years? Non-US models? I thought it'd be interesting to wire up a small LED array (or something similar) and tuck it up on the kick panel since the wiring was already there.... Any thoughts? Thanks, Steve

The A/C setup in my Z looks like it was "meant" to be there. There's a metal mount for some little black canister on the wheeelwell between the cooling radiator and the passenger footwell how-ya-doin'. I always thought it was a dealer installed option but it looks like things were put in the engine compartment for the purpose of mounting the A/C hardware.

Everything on my 260z is original, but the speakers sound bad. Looking at replacing but not sure what size I need. Also, went to local radio shop, and since they haven't seen many old Z cars, they don't know either. Also, they are concerned about breaking/cracking the interior panels to get to the speakers. The location of speakers are the ones directly above strut housing. I think speakers are 4" but not sure. Also, can anybody tell me if an aftermarket radio kit is available for a 260? Thanks!

welllll...... got the battery relocated to the back with a rear mounted cutoff switch on the back panel. at the same time i was doing that, i did the internally regulated 280ZX alternator swap (and did the diode thing) anyway, when i switch the battery switch, the car acts as though the key is in the "ON" position - brake light is on and the distributor (E12-80) "clicks" when rotated. i pulled out a bunch of crappy PO-installed wires at the same time, as well, but those were for the cruise control, etc. anyone have maybe a check off list? i'm terrible with electrical stuff, so any help would be great! better yet, if anyone in san diego wants to take a look..... Jaso…

Thought I'd ask for Zs-ondabrain opinion about the article on Addition of a Relay to a 240Z Starter System found at http://www.biopatent.com/solenoid.html.

I'd like to know if anybody has a good idea or gizmo for letting you know to turn your lights OFF? I don't want to be stuck somewhere with no juice. Thx.

60,000 Volt Flamethrower Coil with a Ignitor II or something a long the lines of an XR700 electronic ignition system. Also, if I do get that, instead of the coil, is there anything else that I should get with it?

Went out to start the Z this afternoon and noticed that after start tach needle was high and then slowly buried itself at 8 grand. I checked all the visible wiring under the hood and found nothing out of place. Any ideas? Tach dead? Silly thing worked fine yesterday. Maybe it's just old and tired like me. Any input appreciated HCH

Hey Gang, I am about to do the XR3000 install on a 79 ZX. The wiring and everything seems pretty straight forward but my question is regarding the stock ignition module (E12-80). Does it stay wired in as is? If so MSA, sells a XR700 module that replaces the factory module, would this be a good idea to do?

I have a 73 240 with 280zx distributer &coil,also has 280zx type 65amp alternator. About 3 weeks ago started missing at slow speeds.

Ithen changed out all the short fuel hoses and both fuel filters. put on my spare rx3 fuel pump still had the miss. Then proceded to the engine pulled all the plugs checked the plug wires and coil wire all looked fine. I just about gave up and was headed to my z guru buddies place and noticed the starter dragged when starting up. I didnt think much about it even though I ha…
