battery relocation cable too short


02dag

Recommended Posts

I have an E30 cable kit, and I have installed this into my car. I havent got a battery box yet, but I am planning to buy the combined strut brace/battery holder from TEP. The cable is about the place where the positive on the battery will be, and this cable is not reaching more than 10 cm through the firewall. Should have had 15 cm more to have some more options regarding placing of the junction box. There is a lot of other stuff attached in that same area(brakes, wiring, steering column etc).

IMO the junction box should be placed in the engine bay, but this causes the obvious problems. battery under the seat is not an option.

Anyone have pictures of the placement of this junction box? Are there different sizes on the cables. Was the E30 battery under the seat afterall?

remember folks, DO NOT USE A WET CELL BATTERY in the trunk unless you use the kind that has provisions for a gas vent tube and that tube is run out of the trunk. batteries give off explosive gases when charging and the trunk is a sealed box to trap those gases.

use a sealed AGM battery instead. lighter too.

i've got two installations under my belt. i go down the driver's side and up over the wheel well like the factory loom. i mount the junction box to the firewall above the brake booster. i do recall having to ensure that i didn't waste any length this latest install; but i made it work. i don't recall having to do that with my first install. therefore, it is possible that the lengths have some degree of variability...

Driver side is the correct side... But you could just put a cool bat cut off or power block there and then extend it!

I had a similar issue; it works out okay if I have the battery mounted with the positive on the left side of the trunk as far as it goes, and then mount the distribution block right against the firewall. I routed it along the driver side under the seat. A bit shorter than I would like, but it will do. I will probably add a cutoff switch in the trunk which will extend the length enough to make it a non-issue.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
