okay, so I know that L-jet uses the point pulses to fire injectors...my main relay is working, so what connections do i need at the coil?
i already have the tach wire, the point wire at the neg and nothing at the positive.... but i have a brown wire and two black wires joined to one both sets of wires having 12VDC on them....what gives? b |

and i also have a white FI wire coming way off and out of the way of the harness which could also be the trigger wire....
why int he hell is a brown wire getting 12V? b |

Britt-
There is a series of 3 L-Jet diagrams under links on my wiring harness website for an L-Jet harness. Seet eh FI harness section. There are actually three different L-Jet 914 harnesses, so does this one match your harness? Maybe its of some help anyway. |

Your L-Jet is from a 1974.
The double relay has a black wire that goes to pin (15) on the coil. The ECU harness pin (1) goes to pin (1) on the coil {also supposed to be black} The 'other' wires terminating at the coil are: pin (1) Green to points pin (1) Black/Purple to Tachometer pin (15) Black (+12V from fuse S9) No brown wires should terminate at the coil. I believe you may have something wired incorrectly. Do you have the wiring diagrams? |

let's do this step by step then:
A)where does the FI "WHITE" wire (that veers from the main bundle and is very long) terminate? Is it ground, or 12V? B ) There is a YELLOW wire over by the relay board...where does this item go? C) There is a set (two crimped together) of BLACK wires....where do these wires go? D) I see a tan wire, maybe even white coming from the relay board connector..12V on it. i tried a couple of combo's and all of them seemed to result in clicking from the dual relay... E) that lug from the dual relay (RED WIRE) is indeed 12V correct? b |

The white wire may go to the AAR. It's just switched +12. The yellow wire is usually the starter wire, esp. if it's heavier gauge than many of the other wires.

L-Jet harnesses are completely different than D-Jet.
Draw us a diagram of your harness. Show how many poles each connector has and their location. Label each branch connector with a letter or number. Scan it and post it or email it to me. bowlsby@sbcglobal.net |

(E) Red from the Dual relay -> To Batttery +12V
((IMG:http://www.914world.com/bbs2/html/emoticons/cool.gif) Yellow from Dual relay -> To Pin II of the (4) pin connector on the Regulator board (ties into starter yellow wire) (A) The white FI wires are numbered if you look closely (I believe in red) If you could get a number, I could tell where it goes. PM me your e-mail and I'll send you the AFC wiring diagram I just scanned for you. |

and the FI wire is labeled "1" which goes to the coil, presumably the negative terminal. b |

I will go look there and trace the wire... Rich |
