• Standard – VVTi batched ignition (chip and coils) are supplied, but sequential NON VVTi ignition is available as an option.
• For GM/LQ9 coils – upgrade should be used with an aftermarket ECU and run sequentially. OEM ECUs require IGF signal produced by the ignition chip. When the chip is removed for LQ9 coil installation, an aftermarket ECU or IGF simulator box is required.

• Factory Speedometer functions by utilizing the ABS system outputs. As long as this system is properly functional, the speedometer will remain accurate. 
• Factory Tachometer remains accurate unless number of cylinders changes. Use Dakota Digital SGi-8 if the number of cylinders has changed from factory.
• A/C wiring utilizes stock BMW fuse box AC relay and wiring. The AC compressor connector must be wired to the chassis’ output AC signal wire.
• Retains functional alternator charge display, oil pressure display, coolant temperature display, reverse lights and wipers.
• Factory cooling fans remain functional if that option is selected.

FAQ & OTHER DETAILS

• Alternator Charge Cable - This item ties the starter/battery directly to the Alternator output, which allows the improved power routing on our harness to eliminate the wire running from the alternator to the fusebox and/or battery while still charging the battery normally.
• Grounding Kit - Our Kit ties a number if engine components to the body of the car and ensures that you will not have issues resulting from poor grounds. The Grounding Kit utilizes Ultra High temp fiberglass sleeving to allow installation under or around exhaust components. Very flexible mounting options allow you to connect the block, head, battery tray, alternator case and chassis to completely eliminate all grounding issues.
• Speedo Signal Conditioning - The Dakota Digital SGI-5 unit for Speed can 'condition' the signal to compensate for cross-platform swaps. If the Option exists to ADD the unit on the harness page for your swap, then you need it for proper speedo operation. Please note that some transmissions (350z, BMW ZF and S15 Silvia for example) do not have a speed sensor and will require a non-harness based solution like a GPS speedo.
  
• Plug-n-Play vs Universal - Plug-n-Play harnesses connect to your car's underhood fuse box for power and to connectors under the dash for gauges etc. Universal harnesses do not need an underhood fusebox to connect to and the wiring for gauges and warning lights is provided as a 'flying lead' which are bare wires labeled with their function.
• Right Hand Drive (RHD) Conversions - If you used ALL the stock LHD chassis connectors for your RHD swap, order the LHD version of the harness. If you used ALL the clip/swap RHD chassis connectors, order the RHD version of the harness. If you used a combination of LHD and RHD chassis connectors, please contact us as our harnesses will need modification.
• Don't See It? - If you have injectors, throttle body, coilpacks or any other item that you do not see on the Options offerings, please contact us. Chances are we can do it!
• Battery Cables / Battery Relocation - The battery must be connected to the starter, so you need a battery cable from the positive battery terminal to the starter main power lug. Typically this positive battery cable also powers up the main under hood fusebox, which runs many of the non-engine items on your car like interior lights, dash power and headlights/taillights. Please make sure you have prepared for this as each install is different.
