Can someone please tell me what each of these relays control? I am also wondering about the silver square one in the middle as it is completely different from the round ones...I just installed a new relay with new headlights; that is the black square relay pictured..
Also, I have lost my turn signals, parking brake warning light (flasher) and drivers side running lights.. (IMG:style_emoticons/default/confused24.gif) OOPS, 74 2.0 |

The silver one is the highbeam relay.

Silver one high/low beam relay and small black one should be the turn signal relay. Check your wiring connectors carefully, you may have disturbed a connection when removing/replacing the fuse panel.
Remember to disconnect the battery when working in this area. Tom |

Yes it does! And that explains why I dont have turn signals. My mistake was installer error by mounting the high low and turn signal flasher in the wrong spots! Yikes. (IMG:style_emoticons/default/blink.gif) Thanks for the information!

That relay in the turn signal flasher relay p[osition sure doesn't look like the correct part .................. The Cap'n Thats because it is not the right part. That was my screw up initially. Put the original flasher relay and I got everythig back. My new delima is this. I was sent a 40a relay for the new headlighs from PP. Tried to install that new relay and I cant get the lights to work. I figured out the following (at least I think I did) for the wires leading up to the relay. Red wire, power White wire, high beams Yellow wire, low beams Yellow/Red wire, high/low switch Ok, so I wired the new 40a relay as follows, Red into the 30 Yellow/Red in the 87 Yellow in the 85 White in the 86 Looking at the pic, does this look like the right way? Nothing is working. I put on the old relay and everything works again as normal. My concern is that the new lights are too much for the old relay and it will eventually fail. Any ideas? |

Any ideas? If memory serves me, that relay is not supposed to be used as a replacement for the stock relay. I have a set of new 100W headlights and they came with relays just like yours, but the instructions with them state that you need to rewire your car and not use the stock wiring and relays since neither was build to handle those loads.

(IMG:style_emoticons/default/idea.gif) Oh, boy. The instructions never said anything about rewiring and the PP website only suggests the bigger relay as prevention of blown fuses and is recommended for 100w bulbs...Gotta look into this some more.. But that aside, I still cant figure out why the relay wont work in the first place and only the old one does... (IMG:style_emoticons/default/hissyfit.gif) |

You have to add a power feed direct to the headlights, and wire the current headlight wiring into the relay. Use the relay to activate the headlights. That way it won't melt the relay or the headlight switch.
Oh..and there is a kit available from JWEST for the 911 that can be adapted to our car. All you have to do is extend the power feed. |

Check the pin assignments vs. the old one, and check the number of pins. I forget when they went from 4 pins to 5, but 5 pin relays (the only new ones available) require adding a jumper wire when used in a car that came with a 4 pin relay.

The relay in question is a standard SPST relay. Not a Hi/Low Relay.
30= Common 87= Normally Open 85= ground 86= + trigger Will not work for Hi/Low but will work for other things. You can either retrofit a SAAB Hi/Low relay ($5-$10) or buy a real replacement ($40-$50). Here is a handy Bosch relay book... Relay_Book.pdf ( 1.08mb ) Number of downloads: 98 |
