If you need one of those vanagon relay boxes that mounts above the coil, I
have one or two.
I tend to want to save that for my own conversions though.
The idea of using the jetta fuse box for just the portion you need is a fine
idea. - might be complicated messing with all those wires on the back of the
fuse box, but maybe not, assuming you might only have a dozen wires max for
the 3 fuses involved. And all the rest you can remove from the back of the
jetta fuse box.
If I was going to do that, I'd route a nice fat battery wire to it, ala
stock, which I'd probably get at the starter, and mount it behind the left
rear tail light so it looked half factory if I could.
Or better, due to the 'exposure to the elements' factor you so wisely
mention, under the back seat.
In a vanagon.........what is in the donor car's 'inside cabin area' for
fuse boxes, relays and ecu ( or was your fuse box under the hood in jetta ?
) whatever was under the dash......... ...........in a vanagon engine
conversion, you put under the back seat, on the left side of the van, just
like 86 & up waterboxers have for their ECU location. It's indoors, dry,
temperature stable, and easy to get at.
leave the wires about 10 or a foot inches too long for lifting it up for
troubleshooting, continuity checking, etc. - so it's easy to work on.
It's really a pleasure to dialogue on gerryvanagon with someone that can
really get their head into something technical, and have an actual technical
and intelligent discussion about it.
So refreshing. I miss it.
Though to be fair there are at times some very intelligent and well
informed posts, even stuff I don't know about. Whadiya know ! . But it's
nice to be able to talk about a signal, or wiring diagram, or something like
that with someone actually interfacing with the vehicle and able to talk
about it intelligently. No offense of course !

Ok. Thanks.
I will probably stick with conventional wisdom and use separate
sockets and fuses for the relays and put them in a box a la the WBX.
In the beginning I thought there wouldn't be sockets with say, 5
female slots. But I was mistaken. (such a newbie!) Plus I felt that
putting relays that were inside the vehicle, outside (so to speak)
would expose the to the elements. Until recently, I didn't know that
the WBX had done this putting them in that "high voltage" box. Partly
cuz I just didn't think, but partly because I had sold that item with
my parts van engine! (embarassed to say I didn't look closely inside
it prior to selling it)
I just thought it would be easier too, to use that perfectly good
Jetta fuse box. Then the relays would be fused, and the connectors
from the engine management stuff would just plug in. Anyhow.....
Thanks again.
Neil.
