Wiring
|
The wiring loom fitment - Having read a lot of build sites about the Tiger supplied loom and how its too long etc I took my time routing it. The next few pictures show the routing of the rear loom. I started by the drivers side tunnel with the grommet on the loom facing upwards towards the dashboard area. |
|
The rear loom is attached along the tunnel top to the brake pipe with cable ties. |
|
The loom then goes behind the drivers seat back, along the top chassis rail and down the triangular chassis rail towards the diff. |
|
Making sure you leave the earth point out. |
|
All the wires go up the short upright except the number plate lamp wires which continue along the spare wheel carrier. |
|
The right hand rear lamp loom. |
|
The left hand rear lamp loom follows the chassis across and hangs down at the end. |
|
The fuel sender loom goes straight up the middle of the chassis. |
|
Whilst the fuel pump loom goes across towards the fuel pump... (Really?!) |
|
I also found out that using cable ties to secure the loom to the brake pipe is an SVA no no. These all had to be taken off and the loom P clipped in place. |
|
The wiring for the pump isn't long enough so its extended. As you can see from the picture all the wiring joins will be soldered and wrapped in self amalgamating tape before being loomed. |
|
The extended wires are then joined to the Tiger loom. |
|
This shows the layout of the front wiring loom which drops down the n/s front tunnel end. |
|
..along the n/s lower chassis rail (leaving out the starter motor loom). |
|
Then up the front chassis rail upright, leaving out the n/s light loom at the top.... |
|
Then the horn, rad fan switch, and rad motor looms. |
|
The Weber Alpha ECU needs to be kept out of the elements. I decided the easiest way to do this would to have it fitted behind the dashboard. I cut a hole in the scuttle and poked it through.... |
|
Fitting the rear
lights..... I started off by using a laser level to ensure both sets of lights were perfectly level. |
|
The rules for the lights
are as follows: Indicators - Max 400mm from edge, min height of 350mm, max height 1500mm, min separation 500mm. Stop Lamps - One on each side, min height of 350mm, max height 1500mm, min separation 400mm. Rear Position Lights - Max 400mm from side, min height 350mm, max height 1500mm, min separation 500mm. Rear Fog - One lamp, on centre line or to offside, min distance from stop lamp of 100mm, min height 250mm, max height 1000mm |
|
The fixing holes were drilled, then a 40mm hole for the rear of the lamp. |
|
>The rear lamps must be vertical so these come with spacer rings move them out at the tops. |
|
The holes drilled for the o/s lamps and the fog lamp. |
|
All fitted |
|
These lamps come with water tight 2 & 3 pin connector plugs so I had to cut the Tiger supplied connectors off and solder new ones. |
|
They work! |
|
>Next I fitted and wired up all the
gauges. There are a couple of mods I had to make to
the tiger loom to get it all working. There wasn't enough
earths for the rev counter so one was added. The fog lamp switch is wired incorrectly on the Tiger loom. The SVA manual says the warning lamp on the switch must illuminate when the fog light is on. The tiger loom has it set up to illuminate when the side lights are on. The easy way around this is to cut the supply for the bulb (red) and join to the fog light output (red/blue). This means the warning lamp only illuminates when the lamp is actually on. |
|
Side repeaters added. The tiger loom makes no provision for these so again, you have to add them in. I wired mine to the wires that supply the dash warning bulbs for the indicators. |
|
Next was the column switches. I have included this diagram to show where the wires
go. If you want to use the sierra indicator/dip switch to dip the headlamps you'll have to wire up an additional pin on the switch (why don't Tiger do this for you in the loom?????) all the details are on the diagram.... |
|
The front indicators. The SVA book
says they have to be a min height of 350mm, and no more than
400mm away from the outer edge of the car. On the Tiger the
rear track is wider than the front so you have to measure
from outer edge of the rear bodywork, not the front. It turned out that I need to space the indicators out another 150mm to put them in the correct position. |
|
The Tiger supplied front indicators use a 10mm nut to hold them in place. I decided the easiest way to extend them was to cut a piece of 10mm threaded rod to 150mm length. Next job was to drill into each end of the rod with a 6mm drill, and then through the side of the rod. This now allows me to thread the wires through.. |
|
This shows the wires threaded through one end. I then locked an M10 nut joining the indicator to the threaded rod. |
|
A piece of 20mm electrical conduit was then cut to 150mm and placed over the rod to make it look a little better. |
|
The new extended indicators
were then fitted to the nose cone and secured with a large
repair washer and an M10 nut. Once the SVA is over I will shorten them again. |
|
The headlamps were next on the list. The mounting base of these lights is wider than the bracket. I cut the mounting supports down either side, so they didn't protrude. |
|
Once the lamps were bolted in place I wrapped the brackets with self amalgamating tape to hopefully give me my 2.5mm radius. |
|
I then fitted some plastic tubing over the headlamp wires. |
