1973 Rebuild

[Matthew Abate]

Finally done with the body harness. In addition to deleting the wires for the speaker and antenna, added a provision for some kind of third/auxiliary brake light next to the license plate light wires, switched to a euro/JDM wiring configuration for the rear combination lights, and added wires for a 12V power supply. Also, I used fuzzy Tesa tape for most of it to reduce potential rattling and their chemical-proof tape near the fuel system, just in case.

Question: what is this 52mm hole in the firewall under the battery tray for?

Ehm.. i think it's a "not original" hole?  maybe one day you find out for what it was made.. i would put in a big rubber (closed) tulle.

Since its in a stamped portion of the firewall I'm guessing it was an addition from a PO

[Matthew Abate]

Yeah, that’s what I was afraid of.

☝By the way, does anyone know what this tab is for? I assumed it’s for a clip to hold the coil wire because it’s similar to the tabs for the plug wire clips.

My 73 has a wire clip for the coil and distributor/water temp sender wires on that tab.  Here's the part No.

Am I misreading that? I’m not finding anything when I search 22472-n3301.

Yep, 22472-N3301.  I'm not finding it either on the web, except for here: https://www.carpartsmanual.com/datsun/Z-1969-1978/electrical/wiring/to-jul-76/23

Maybe only a July 73 thing?  

[Matthew Abate]

I see that N3300 was used on the manual. Any idea how it was different from N3301?

[KenFirch]

Haven't a clue.  Mine shows no signs of ever having an automatic.  Not sure what difference between AT & 4SP could even warrant a change in that area of wiring.  Misprint maybe?   I see a few of them on BAT pics, even earlier years, look the same.

Just checked on my Mfg 12/70 car - 4SP. The clip looks the same as the one pictured but there are no markings at all on either side of the plastic wire clip.

If it was an automatic at one time there is a trans kick down bracket above the gas pedal and you will not have a bump stop on the firewall where the clutch pedal depresses. My 78 conversion proved this and there is extra wiring in trans tunnel.
