Z4M: Leather Z Triple Gauge Install

This DIY post summarizes the process of installing the Z4 Complete Gauge Kit which can be found here. This post also aggregates other posts related to the topic.

In general the Leather Z kit is well designed and comes complete with gauges, mount, sending units, wiring, and detailed pictured instructions. The posts below provide you with additional details to make your install go smoothly. My install was for the S54 gauges and included the Leather Z Power Socket Relocation kit found here. Since I did not have the luxury of doing this in one shot I broke the process into six steps and completed it over several days allowing me to drive the car after each step. All together everything worked upon first try. I would recommend this DIY to anyone with moderate or intermediate mechanical skills.

Step 1 - install the Z4 Power Socket Relocation Kit adding the radio Aux In.

Step 2 - mount gauges and hook up to dim lighting.

Step 3 - install the water temp sending unit which requires draining and replacing the coolant.

Step 4 - install the oil pressure sending unit which requires disassembly of the air intake system.

Step 5 - wire the sending units tie wrapping along the away finally passing through the firewall to the gauges.
See post above for wire routing tips.

Step 6 - connect the gauges to the sending wires and switched power.
See this post for tips for finding switched power (not in the instructions):

Pressure brake bleeder

I am not endorsing this vendor because their service has been not completely satisfactory at times, but this product is an excellent tool to have that allows easy one person flushing and replacement of brake fluid for the brake and clutch system.

CTEK 7002 Battery Charger

http://www.ctek.com/EN-US/eLearningUS/Default.aspx

http://www.ctek.com/Manuals/new_US7002_EN.pdf

When charged in normal it draws .03 ampere.
Battery Tender draws .06 ampere.





I added a aluminum plate on the bottom of the CTEK with 1/2" height spacers.
Was going to match the bottom of the CTEK, but too much time doing it by hand.

1 each Plate 4" x 8" x 1/8" aluminum. (polished with 220 wet paper)
2 each Spacer 3/8" hex, 1/2" height w/ 8-32 male / female.
2 each Nut nylon lock stainless.
2 each Screw 8-32 1/2" counter sink stainless.



Back on the garage floor doing its thing.
