what connectors for high amp wires?
At the moment I've used large choc blocks for setup testing.
These wires are high amp and one is a wire direct from battery to ignition which then shares to Ignition / ACC wires coming from the ignition going to
the CBS fuseboard.
that will be running - headlights, sidelights, indicators, heater/aircon, horn, rad fan, dials, wiper motor and washer jet, brake lights, radio
Wired direct to battery - alternator, fuel pump, ecu, starter motor (only relay off ignition wire (seperate wire) to activate all the engine
requirements in a rear fusebox)
I have wired in the additional fusebox from the MR2 I used and the circuit protector amp there is 50amps on one and 80amps on the other, with overall
protection of 120amps. Now that was for an MR2 with all the gizmo's obviously.

I would have thought sidelights ( at least ), horn and emergency flasher, perhaps radio ( but your choice ) shouldn't be via ignition. Reverse
light ? Fog light ?
Fuel pump and ecu direct to battery ?
I'm addicted to brake fluid, but I can stop anytime.

Sorry id abbreviated quite alot.
The CBS fuseboard does the relevance in terms of power at the right moments, it has a direct battery feed which feeds relevant connection points (i.e
sidelights, hazards etc..)
then gets a wire from ACC on ignition and again feeds relevant points (radio, indicators etc...)
and then finally ignition feeding again relevant points (fuel pump (if i was using it etc...)
fog will be off headlights to meet IVA requirement on when they work and reverse from the rear power feed.
The way the MR2 setup works is it has a rear fusebox / relays. a thin relay wire from ignition effectively turns on everything in the engine
compartment (fuel pump, ecu, injectors, ignitor) via the relays. so all of this powered direct from the battery (turned on via relays) and puts no
high load through the wires i'm asking about.
hope that explains a bit better and below is a pic of the actual fusebox at the rear with relays and fuses. Worked out quite nice as i can use MR2
manuals for diagnosis of the whole engine system not just the loom.

Shouldn't the wire go straight from the battery to the fuse box with no breaks/ connectors needed? Why is the wire not just a straight link or
am I missing something

Correct; battery to fusebox is direct (its in the first line of last post)
The wires which I have had to join with a choc block (for testing) and interested in getting high amp connectors for are;
Battery to ignition
ACC from ignition column to fusebox
Ignition from ignition column to fusebox
Its my poor explanation, that's confusing matters. You should of heard me when I first looked at the electrics

One of my many other hobbies is RC modelling. The increasing use of LiPo power in high amp applications for modelling means that there is a plethora
of connectors available for linking batteries and speed controllers and motors.
Google deans connectors or search for XT60 connectors (or something equivalent)
I hope this helps?

Quick check on them and they are perfect at handling over a 60amp load.
thanks very much!
