Replacing positive battery cable - grounding question
Hey guys, im rebuilding my battery harness here.
Im starting the process of rebuilding my wiring harnesses here and the negative terminal has a grounding point about halfway down that bolts to the chassis.
Is this grounding terminal something i can replace with a generic part? If not, how would we replace the negative terminal here and retain the stock grounding location?
Heres a picture of that terminal.

yep, instead of one cable, you need two. one from the starter to this ground, and the second from that ground to the battery

I'm like 1.5 years deep into the harness replacement job, and I'm still in the planning / parts-gathering phase. Granted I am trying to get everything done at once to minimize downtime, but still.
Thankfully pzr2 and JerryLH3 have already done a lot of the information-gathering work for us.
Also, you might find this info useful: https://www.rbracing-rsr.com/wiring_ecu.html
That page has a ton of information, although it does cause me some analysis paralysis. Whenever I think my planned harness is good enough, there's always one more thing I see at that page that I wonder about adding. Printable heat-shrink, epoxy sealed boots for the connectors, concentric twist, service loops...

Man I should get that reference website finished. I posted about this in another thread awhile ago but for the 1st gens.
That style of connector is referred to as a nailhead style terminal. I'm sure the OEM is Yazaki/AMP or something but I have an old Delphi (they are now called Aptiv) catalog that shows P/N 12015306 works for the housing + an appropriate Packard 56 series female terminal (for 20AWG wire, both 12124512 & 12124513 work). It's light gray as opposed to the natural plastic in Mazda harnesses, but I haven't been able to find an equivalent with another manufacturer yet. Mouser still shows stock of it.

@pzr2 thank you for that and yes i did get them switched, my bad.
and let me know if you need any help with that website and if i can contribute in any way. i know you had a thread about the S5 harness and @JerryLH3 had an S4 harness but his seems to be the 88 year which for some strange reason differs from the earlier 86-87 S4 harness. im rebuilding my S4 harness from my 87 FC and i think i have most of the connectors
