BMW 556uw bypass wiring

2003 BMW 330xi manual transmission 556uw Gallo Tech push button starter 3 So I installed the push start and then I installed the bypass module 556uw. Car won't start but it will turn on all the accessories when I use the push to start button. If I insert the key to the second position (acc), the push button works flawless. I'm assuming that it's the bypass module. I used both first and second options (both options without the module sensor ring). Second option is what I have read works with this car (European). I cut one wire from the factory sensor ring, attach the black wire to the ews side and tied the BLACK/ white and BLACK/ red to the factory sensor ring side. My question is, does this vehicle have a key sensor and if it does which wire is it (vehicle) and if it's negative (green wire from module) or positive (violet wire from module) Or am I missing something entirely or a better way of doing this?

Model # GTS–3 (without Remote Start) Push to Start for wire colors! Did you put working sacrificial transponder key in box? Made connection to the Bypass (-) status Blue turn on wire from the WHITE/ Red Disarm (GWR) of Push to start? Connect ignition wire (Brown) from Push to start to Bypass (Pink) Ignition input also, as it may be required to keep the Bypass live while vehicle is running for BMW? Post back if you still have problems with all the connections you have made between the Bypass, Push to Start and the Vehicle.

Thank you Lurch228 Yes, a brand new transponder key and tested to work with no issues. (it was a real tight fit and I may have to retro fit the cover) GTS-3 Connections GTS= Red --BMW Ignition Harness =RED / Green 12 Volt Constant. GTS= Blue ACC --BMW Ignition Harness =Purple (IGN 2). GTS= Brown (Ign1)--BMW Ignition Harness =Green (IGN 1). GTS= Orange (starter)--BMW Ignition Harness =BLACK/ Blue (Starter). GTS= PURPLE / white (start enable input-)-- BMW Clutch Pedal Harness. GTS= WHITE/ red (GWR) ---556UW=blue 556UW= jumper mode 2 556UW= antenna BLACK/ white & BLACK/ red (cut) BMW Transponder Ring side 556UW= antenna black (cut) BMW transceiver side 556UW= Black to ground 556UW= Red to constant 12volt 556UW= blue to GTS=WHITE/ red (GWR) Pink wire has no effect with the GTS brown wire (IGN 1) I didn't bother listing connections for door locks/trunk unless you think it may help. I was pretty sure I tested the ACC/IGN1 on the vehicle with a volt meter but on paper is sure looks like its backwards...That would be the first thing Ill check and the second is possibly the clutch pedal - PURPLE / white may have been connected to the wrong wire of the 4 available...no info on which one is a negative trigger let me know what you think....its a midnight project after work so lack of sleep and light may contribute to my mental handicap

Foot Brake is needed to enter start mode for the push to start system. Don't see where you have it as being hooked up to the push to start? C3/18 BLACK/ White FootBrake input (+12v)

Also need to hook up C3/13 White (Option 2) to additional relay to power the Ign 2 and hook up the Blue ACC wire to vehicle ACC wire for proper operation.

Well I tested both wires IGN 1 and IGN 2 on the car, and they are both constant 12 volt when the engine is on. I switched them, I treated bmw IGN 1 as GTS ACC and bmw IGN 2 as GTS IGN 1. Same outcome. There is only 5 wires to work with. RED / green and RED / blue = constant 12 volts Starter = BLACK/ blue Ignition 1 = Green Ignition 2 = Purple I am wondering if setting some of the functions on the GTS (Manual transmission) need to be turned on/off (ignition 2 off/on during engine start). Not sure if it matters since I didn't use/have that option.

sorry I was posting before I saw your reply I will hook up the brake again (BLACK/ white...wasn't sure if that was just an automatic transmission safety issue. Nothing I have read or found lists an acc in a wiring diagram which is why its confusing and both ign1 and ign2 are testing like an acc (key in position 2) as an acc and both are constant when the engine is running (position 3). I'm off to do the foot break and get a relay ready for ignition 2

A ribbon cable which connects the switch to the module will be exposed. With the switch facing towards you, you need to interrupt the fourth wire from the left with a relay.

The foot break BMW BROWN / white with the GTS BLACK/ white(13)and I have a relay white is hooked up again to ignition 2 BMW purple wire..no result. relay is functioning as intended. Am I not tapping into the correct ACC wire? GTS blue to BMW ignition 1 (green)?

If both Ign wires work the same with key the you will need to Enable Ign2 to Duplicate the the action of Ign1. In the Table 1 "Function Option Chart on (page 8). Set 2 to Enabled during Engine start.
